Typical of what we like to think of as the company's "mysterious charm," the feature has been unveiled six months later with a brief post on the Twitter blog. The new geotagging capabilities can already be seen in certain third-party apps and might even come to the web interface sometime soon.

Apps such as Birdfeed, Seesmic Web, Foursquare, Gowalla, Twidroid, Twittelator Pro, and many others are already supporting location-based data for tweets.

"The added information provides valuable context when reading your friends tweets and allows you to better focus in on local conversations," writes Twitter platform/API man Ryan Sarver in the blog post.

"Now you can find out what live music is playing right now in your neighborhood or what people visiting Checkpoint Charlie are saying today about the anniversary of the Berlin Wall. These are only the beginning and we are really looking forward to seeing the creative uses emerge from the developer community."

As are we! But we might hold out on enabling the geo-tastic feature just yet. We've still got a few stalkers to shake, and we're waiting for the inevitable bugs to surface before we trust our favorite microblog with our favorite haunts, too.

In the latter parts of the study, the company looked specifically at social network membership data for users of the AOL, Gmail, Hotmail and Yahoo webmail services. Not surprisingly, the study found that Facebook was the most popular network across the board. What's more interesting is how well MySpace fared in some cases. On both the Hotmail and Yahoo webmail services, Facebook only had a small lead. Here, around 20% of all Hotmail and Yahoo webmail users were found to be on Facebook and MySpace. What does this reveal about the Hotmail and Yahoo user base? That they're a little more behind the times? Or that they've been around on the net longer and at one time had created (and possibly now abandoned) their MySpace pages? Unfortunately, the study can't provide us with these sorts of answers.

The study also showed that Twitter is far more popular among Gmail users than anyone else. In fact, on the other services, it's 4-5 times less popular than Facebook. We would like to think that's because Gmail users are just more web-savvy and cool, but it's possible that it's because they're just younger than everyone else.

Not surprisingly, LinkedIn is the least popular social network, but as Rapleaf points out, many LinkedIn users may have registered with their business email instead.

Participation Levels - Hotmail Users have Most Profiles, Gmail Users Better-Connected

When it comes to how the webmail users participate on social networks, Rapleaf found that the majority of the users have only one social media profile. But the service where the average number of profiles is the highest might surprise you - it's Hotmail. There the average is 2.5 profiles per user. Hotmail is followed by Yahoo, then AOL, and it's Gmail users who have the least number of social media profiles. That finding seems odd considering that Gmail users are younger and more likely to use Twitter in addition to Facebook. In fact, it almost seems like this data doesn't even fit with the rest of the study.

However, the discovery that Gmail users are better-connected than the other users makes more sense. On average, Gmail users have the most friends on social networks with 46.2 friends while Yahoo users have the least with 40.0.

Since again, Gmail users tend to be younger than the rest, it goes to reason that they would be in a demographic where their peers are more likely to have social membership profiles. Older webmail users, meanwhile, are still signing up for these sites. Although baby boomers and other middle-aged folks are joining sites like Facebook in droves these days, social networks are still dominated by the young.

Methodology

For the Rapleaf study, the company sampled 120,000 webmail accounts from users with @aol.com, @gmail.com, @hotmail.com and @yahoo.com email addresses. They then looked into the users' age, gender and social networking data by collecting information from public social media profiles. Obviously, in doing so, they've skewed their findings a bit, as the company notes in their original blog post. However, the sample size is large enough to form some conclusions about the members of these services, even if it relied on a particular subset of users.

Le Meur told us that a native Windows client was something that Seesmic's users had been requesting for quite a while. The Seesmic team worked on this new client for the last few months, though the company managed to keep this development under wraps and today's release comes as a surprise. While there are quite a few good native Twitter clients for OSX, the most popular Twitter clients on Windows are currently AIR apps.

Features

Being a native client, Seesmic can now also make use of some of Windows' built-in features like a system-wide spellchecker or Windows 7's location services. While Twitter hasn't launched it's location API yet, Seesmic will now be able to tab into this data quickly.

The new client will also allow users to drag and drop their friends' avatars into user lists.

Just like the current beta version of its AIR app, Seesmic for Windows will support Twitter's userlists and while the look and feel is similar to the AIR app, the Windows client also features vertical tabs in the sidebar that allow users to quickly switch between different views (all, accounts, userlists and searches).

Plugins for Seesmic

For developers, of course, the new plugin infrastructure also means that they can now offer their services directly in a Twitter client. The current version already showcases plugins from TweetMeme and MrTweet. According to Le Meur, this will also allow other Twitter-like services to build their own plugins and build their own columns in Seesmic without having to establish a formal relationship with the company. In a few weeks, Seesmic will launch a plugin gallery to showcase these extensions.

What About the AIR App?

Seesmic will continue to develop its Adobe AIR client for the time being, though chances are that the company is also looking at developing a native Mac client.

Update: There was a mistake in Sysomos' report. Twitter.com's share actually grew slightly from 45.7% in June to 46.7%. We apologize for the confusion.

Compared to Sysomos' last study of Twitter clients in June, Twitter.com's share fell from 55% to 46%. As Twitter's growth is slowing down, these numbers make a lot of sense. New users tend to use Twitter's web interface at first and then migrate to a third-party client. If Twitter.com's market share among Twitter clients is dropping, then this can be seen as a strong indication that the number of new signups is going down as well.

TweetDeck: The Client of Choice for Active Twitter Users

TweetDeck doesn't just have the largest number of users, it is also the tool of choice for the most active Twitter users. Sysomos analyzed the number of tweets posted by active users based on their primary Twitter application. On average, TweetDeck users send out 1.24 tweets per day, followed by Seesmic users (1.18 tweets/day) and HootSuite (1.11 tweets/day). Users of all the other popular clients like Tweetie, Twhirl and Twitterific update their status less than once a day. Those who prefer Twitter's own web interface only send out 0.67 tweets per day.

How Many Clients Do You Use?

Sysomos also analyzed how many third-party clients Twitter users normally use. Looking at active Twitter users only - those with at least 50 tweets in the last 5 months - the study found that 82% only used a single application. 14% used two applications, 2.35% used three and then the numbers drop off quickly. Only 0.01% of all active users used 6 or more clients. Chances are that a lot of active users use different mobile and desktop clients (Tweetie on the iPhone and Seesmic on the desktop, for example). This would explain why quite a large number of users use two clients.

The Suggested Users List, commonly abbreviated "SUL," has long been a source of controversy for the company. Meant to offer a helpful introduction to Twitter novices about what sort of interesting people, companies, and services can be found on Twitter, the list has angered many who felt it was a way Twitter could show favoritism towards some accounts while ignoring others potentially more worthy of inclusion.

Noted tech legend Dave Winer argued that Twitter was taking an editorial interest in their service, and one that rapidly inflated the follower counts of those blessed with Twitter's "gift." Meanwhile, Mahalo CEO Jason Calacanis offered the company half a million dollars for three years on the list. (Twitter didn't take him up on the offer.)

The benefits to getting on the list are great indeed. Users added to the SUL, gained on average of 53,000 new followers after being on the list for a week and 170,000 within the first month. Some users even gained as many as 370,000 in the first 30 days.

For a service favored by marketers, businesses, and other self-promoters, placement on the SUL was a surefire ticket to Twitter stardom. New followers meant more traffic to the websites linked in the Twitter updates and more traffic meant more money could be made through on-site advertising. It was almost as if Twitter itself was writing you a check.

Thankfully, in this case, Twitter has listened to their community and is planning on a more egalitarian system. The only question now is how will they know which accounts to suggest? Of course, there is still the old stand-by method of importing your email address book to suggest users you already know who are on the service. But what Twitter plans on offering sounds a little more robust. Perhaps they will introduce an algorithm that takes into account a Twitter user's "authority?"

If that's the case, Twitter may be jumping out of the proverbial frying pan and into the fire. This is because there isn't solid agreement as to how "authority" should be calculated. Late last year, Twitter app Seesmic creator's Loic Le Meur started a heated back-and-forth on the matter when he wrote a blog post which said that Twitter should rank search results by the number of followers you have. More followers meant more authority, he said. Social media guru and blogger Robert Scoble quickly countered saying that the number of people you follow was actually a more important number as is the number of retweets, the number of favorited tweets, the number of inbound links to a tweet and the number of clickthroughs on an item in Twitter search. Soon, the entire tech blogosphere was engaged in the discussion with seemingly every blog weighing in with their opinion.

And this was only a casual discussion among Twitter users based on one person's suggestion. Imagine what an official policy change by Twitter will lead to! Clearly, no matter what the company comes up with, it's bound to be heavily debated and discussed. In any event, it will definitely be worth the wait to find out what that is.

In Seesmic's web interface, users can now simply hover their cursor over profile pictures and a menu will appear. This menu, among other things, allows Seesmic's users to add others to lists. One nice aspect of the web interface is that it auto-updates lists when new tweets come in. The desktop app - at least in the current version - doesn't do this and forces users to manually refresh lists to see updates.

Geolocation

In addition to supporting lists, the new version of the web client also supports Twitter's geolocation API. Seesmic users can't share their locations, but whenever a Twitter user broadcasts location data, a little pin will appear underneath the profile picture, and hovering over this pin will bring up a map. Only a few users actually have the ability to broadcast their locations at this point. Twitter is only giving platform developers access to this feature for now, but it should soon become a standard feature in mobile clients like Tweetie 2 and Twitterrific.

Over the summer, we noticed that Twitter was submerging some adult-themed trending topics, and we noted the absolute need for more top-down policing of the trends list, which should be available for surfacing interesting and timely items to engage users. Today, Twitter has finally acknowledged the brokenness of the feature and has stated its intentions to fix the issue.

"So, today we're starting to experiment with improvements to trends that will help you find more relevant tweets. Specifically, we're working to show higher quality results for trend queries by returning tweets that are more useful. The improvement won't be very noticeable at first, but this is a small step toward unearthing more value in search and getting you more relevant results."

We are interested to know exactly how this new algorithm will work. Clearly, the wisdom of the masses has proved to be anything but. We hope that, beyond editing the tweets that qualify as representatives of a given trending topic, Twitter will acknowledge that they already do police trending topics, and we hope they will do so with greater diligence, intuition, and intelligence.

Vulgarity and inanity aside, we worry about dupes. For example, right now, FortHood, Fort Hood, and FtHood are all trending topics. Likewise, every time a good football game rears its majestic head, we see the name and city of each team start to trend, along with NFL and the like.

There are many ways in which trending topics are busted, useless, and irritating - hence, many opportunities for making them customizable, interesting, and useful. We're sensing an opportunity for third-party apps to step in here. Traditionally, Twitter is late to the game in making official features from ideas third-party developers have been working on for ages. Unless Twitter takes some impressive and noticeable action, an app might fix trending topics before Twitter does.

Over the course of the year, there have been countless reports - some more substantial than others - but all with the same message: Generation Y is just not interested in Twitter. The reports generally cited members of this demographic as saying Twitter was "pointless" and "narcissistic."

Apparently, that's beginning to change. Well, maybe not their perception of Twitter, but certainly their use of it. Today, Twitter is now the second-youngest of the top four social networking sites. Its median age is 31. MySpace's is 26, LinkedIn is 39, and, as noted above, Facebook is 33.

When looking at specific younger demographic segments, and not just Gen Y, you can see strong Twitter uptake over the past year. For example, 37% of those 18-24 now use Twitter when only 19% did back in December 2008. And in the slightly older 25-34 bracket, a portion of which could still be considered Gen Y, 31% are now using the service compared to only 20% in December of last year. Combined, these two groups account for more than half of Twitter's network.

Why is Gen Y Now Flocking to Twitter?

So what gives? Why has Gen Y seemingly changed their minds about the social microblogging network that only months ago they avoided? A recent AP article offered up some ideas including the influx of celebrity tweeters, pressure from teachers or bosses, and it even hinted that Gen Y'ers entering the workplace have found value in the network for business-related purposes. That same sentiment was shared by Meredith Sires of Gen Y trend-watching site, YPulse. She theorizes that the rapid growth in the 18-24 demographic has to do more with the recent college graduates segment of that group finding ways to build entirely new online contact lists and create new identities more closely tied to information-sharing.

However, there have not been any in-depth studies that detail all the various reasons that Gen Y has chosen to adopt the microblogging network. To date, everything cited consists of just theories and speculations based on anecdotal evidence. But while all the ideas have merit, the theory that rings truest to our ears is the one put forth by Craig Watkins, a University of Texas professor and author of the book "The Young and the Digital." He says that what we're seeing is "...a kind of closing of that generational gap as it relates to technology." In other words, young and old alike are joining the same networks and socializing in the same spaces.

At this point, we would have to agree. After all, Gen Y (or Gen Z for that matter), hasn't all of a sudden flocked to some new social networking site where the majority of the online user base mostly consists of their peers. Although some niche sites like FML, Failblog, TextsFromLastNight, and Sporcle have apparently attracted this young crowd, their numbers are dwarfed by those of Facebook, Twitter, and the like. It seems as if Gen Y is simply content to join the older adults on the top social networks of today and not strike out on their own...and vice versa. The older social networking users, in turn, never really set up shop on networks designed just for them like the (now "hibernating") Boomj, a social network for baby boomers, or the online old folks home eons.com. They, too, have gravitated towards Facebook and Twitter.

Will this ever change? Will there ever be another network dominated by the digital youth? Of course no one can know for sure, but odds are that unless it's a closed-off network where entry is barred to those over a certain age, any new social network will have trouble keeping the grown-ups out these days. And even if some such network ever sprang into existence, it may struggle to attract the Gen Y members it desires - especially since they're so content to socialize on the sites they already use. And now that they've added Twitter to that list, the challenge to draw them away to yet another social networking site may prove even more difficult than before.

Note: statistics in this article are from Pew Internet's Recent Report on Twitter for Fall 2009

What makes this an ingenious member engagement tool for Digg, is that sub-par articles with a high number of comments are likely to incite action. In the past, many of us simply ignored the sensationalist stories that plagued the lower echelons of Diggdom. Nevertheless, with trolls being a driving force in the determination of trends, users will find themselves clicking through simply to right the wrongs in the Digg universe. While real-time shopping notifications like Woot's Twitter account incentivize users with deals, Digg knows that its members will keep coming back to maintain a sense of justice. The company will be rolling out the trends feature in the near future.

The new Twitter links, however, are a whole new story. If an Amazon Associates member takes the time to re-write the text into their own words, there's virtually no way to know by looking at the post that the Twitter update is actually an ad.

Is Amazon Spamming Twitter?

In the past, several legitimate companies have diluted the Twitter stream with promotions and contests encouraging Twitter users to "tweet to win" so to speak, by pasting in some sort of marketing message into the "What are you doing?" box or by appending a promotional hashtag to their everyday messages. But unlike these company-run Twitter promotions, there's not a hashtag to use or any specific wording that has to be tweeted in order to participate in the Amazon Affiliate program. All anyone has to do is tweet links along with the message of their choosing.

Because Amazon's marketplace is extensive in terms of the products it sells, there's a wide variety of things which can be promoted. No matter what a Twitterer's particular interest is: music, politics, technology, etc., there's bound to be hundreds of things that could be mentioned in their Twitter stream without the posts appearing to be an ad. In fact, there's a good possibility that they would have been talking about these products anyway throughout the course of the day...they just couldn't have made any money off of them until now.

Hidden Advertisements

The problem with this sort of "hidden" advertising, though, is exactly that: it's hidden. This is the internet's version of "product placement" - subtle advertising in plain sight yet never clearly identified as such. Was your favorite TV star using a Macbook? Was he drinking a Coke? Already commonplace in Hollywood, these almost subliminal advertising messages permeate our consciousness every time we turn on the TV. Now that same sort of hidden ad will soon show up in the Twitter streams of your favorite tweeters.

Soon they'll start promoting a great book they just read, a DVD they liked, or one of a million other things pulled out of Amazon's vast inventory. None of it will sound out of place given the types of informal conversations that take place on Twitter every day. You won't even know that they're advertising to you until you click through on the link and find yourself on an Amazon.com webpage - and even then, you may not be sure. Was that a referral or were they genuinely just linking to the Amazon website to be helpful?

Will the FTC Step In?

Another question this raises, at least here in the U.S., is whether or not the FTC will get involved. Having recently taken steps to make sure that bloggers were properly disclosing freebies or payments received by companies whose products were being reviewed on their sites, one has to wonder if they'll now be tempted to monitor the undisclosed advertising that's about to explode on Twitter.

Amazon could have avoided the potential threat of government involvement (not to mention the accusations that they're "spamming Twitter") by generating their links using their own proprietary URL-shortening system, something like amzn.com or amz.com for example. That would clearly identify the tweets' purpose. But instead, they opted to make their links with the URL shortener bit.ly, the one that Twitter itself uses by default. This makes the Amazon links indistinguishable at a glance from any other shortened link posted to Twitter. There's no way to tell if a tweet is an ad unless the Twitter user left Amazon's auto-generated text in place. Of course, no one is going to use that text except the laziest of Twitter spammers - people you're probably already avoiding.

Tell Amazon What You Think with #AMZNSOT

Today, many Twitter users are coming out against this new type of Twitter-fueled advertising, registering their complaints via tweets marked with the #AMZNSOT hashtag, the official tag used to give Amazon feedback about the system. These users are already branding this new effort "spam," saying things like: "Amazon now gives you cash for spamming on Twitter? Oh, swell," as Twitter user TwitBin says. "Does this just mean more Twitter spam as people try to make money?" asks NickHerbert. But there are just as many Twitter users saying nice things about the new system too, calling it "cool," "awesome," "sweet," and even claiming it "rocks."

You can give Amazon your two cents as well by updating Twitter with your thoughts and including the #AMZNSOT hashtag along with your message.

Whether you think the new Amazon Twitter integration is good or bad, there's no doubt that it will be a major game changer for Twitter. As it blurs the lines between conversation and ads, people seem to think that Amazon has either created something of genius or has ruined Twitter as we know it. Few seem to be undecided when it comes to their feelings about this issue. The question is now: which side will end up being in the majority?

In the desktop client, Seesmic integrates lists in its sidebar. To add a list to the deck, you just click on the name of the list. Using these userlists is just as easy as creating a persistent search in Seesmic. Seesmic has also added the option to add users to a list right from the desktop.

This is still an early build and some features are still missing. Seesmic's CEO and founder Loïc le Meur told us that Seesmic's users had been asking for basic lists support and that the company wanted to get this feature into its users' hands as soon as possible. Because of this, some features haven't been implemented yet.

In the build we tested, we couldn't create new lists, for example. For now, list columns also don't update themselves. Instead, users will have to reload them manually. As le Meur told us, users would quickly hit their API limits on Twitter if the lists auto-updated. The company is working with Twitter to find a better solution. For now, the lack of auto-updating lists is an annoyance, but not a deal-breaker.

Le Meur stressed that this was still a preview version and that the company plans to ship more comprehensive support for lists in the final build.

Coming Later Today

If you want to give it a try, just sign up for Team Seesmic and you'll be notified when the new build arrives.

Without sufficient anti-virus and malware protection programs installed, social networking users can easily become victims to these ever-evolving attacks. However, the best way to avoid becoming a victim yourself is to be aware of what's out there and what sorts of things you should avoid. Below are the best practices which you should use on Facebook and Twitter in order to keep yourself safe.

The Problem with Malicious Links

One of the most common vectors for attacks are malicious links posted either to Twitter or to your Facebook wall. In the past, such as with the malware known as Kooface, the troublesome links could be easily identified because they would often use a consistent phrase followed by a URL. For example, in August, Koobface was posting links that read "my home video :)" which was followed by a URL and then a random component on the end such as "HA-HA-HA!!", "W.O.W.", "WOW", "L.O.L.", "LOL", ";)" or "OMFG!!!"

Although the end piece changed from tweet to tweet, the message itself remained the same. However, security researcher Costin Raiu of Kaspersky Lab tells us that easy-to-identify messages are not as common anymore. Today, it's much harder to identify malicious links thanks to two newer techniques being used by hackers. Below those two newer methods are described in more detail as is the tried-and-true method of spreading malware via email.

Method 1: Hijacking Twitter's Trending Topics

The first technique, which really became popular in August of this year, involves hackers creating Twitter new accounts and then posting messages related to whatever trending, or "hot," topic was being heavily discussed on Twitter at that time. This would allow the post to be aggregated in Twitter search results where unsuspecting users would click on the included link. The text accompanying the link would be intriguing to those interested in the subject, enticing them to click through.

Method 2: Hijacking Legitimate Accounts

The second technique involves infiltrating legitimate accounts through phishing attempts and other methods so that the hacker essentially has control over a "real" account. After control has been established, if on Twitter, the hacker will then tweet out links that redirect users to malware-infected sites. Because the tweets come from an account that already has an established set of followers, those reading the tweets assume it's safe and don't hesitate to click the links.

After infecting the account of a Facebook user, malware often uses that particular person's account to spread, too. As with the malicious links on Twitter, because it appears that the links posted are from a trusted friend, other users don't realize that the posted link is harmful.

On Facebook, one of the most problematic malware programs is Koobface, a particular type of malicious software that sees 20 to 30 new variations per day. Despite the number of variants out there, Koobface's M.O. is relatively consistent: it tricks people into clicking links. These links appear on social networks like Facebook and Twitter, but also on MySpace, hi5, Bebo, Friendster, and others.

Method 3: Dangerous Email

A third method to encourage social networking users to click on infected links is the old but still effective technique of sending out spoofed email. Hackers can create email messages that appear to be sent from a social networking site. The messages prompt you to "update your account" or open an attachment containing your new password among other things.

Although many users are now wary of email, these techniques are still being seen in the wild, so it's clear that to some extent they still work.

How To Stay Safe

There are a number of best practices that you should follow in order to stay safe and avoid infection. They are as follows:

1. Don't assume a link is "safe" because it's from a friend: As noted above, your friend's account may be infected. You should never assume that a link is safe just because a friend tweeted it or posted it to your wall. Use your common sense. If it doesn't sound like something they would say, be wary, don't click. If you're unsure, try to contact them through another channel and see if the link is legit.
2. Don't assume Twitter links are safe because Twitter is now scanning for malware: In August, Twitter partnered with Google to use Google's Safe Browsing API, a technology that checks URLs against Google's blacklist. This prevents spammers from posting malicious URLs to Twitter, but it does NOT prevent them from posting shortened URLs which direct users to those same malicious sites. It's better than no protection at all, but it's not going to keep you entirely safe.
3. Don't Assume Bit.ly Links are Safe: Earlier this year, Twitter's default URL-shortening service Bit.ly, began warning users of malware. Bit.ly also uses Google's Safe Browsing API along with two other blacklists to identify malicious links. Although the service doesn't prevent users from posting these links, it will warn upon clicking that the site being linked to is infected. However, as Raiu tells us, this is not 100% effective either. Kaspersky has identified a number of malicious links which Bit.ly did not block. However, you can assume that Bit.ly is generally safer than the other URL-shortening services because it uses this technology and because the hackers are generally avoiding this service at the moment because of its built-in protection. But it is not completely safe - nothing ever is.
4. Use an up-to-date web browser: Kaspersky recommends using the latest version of your web browser and keeping it up-to-date with the necessary patches. That means Internet Explorer users should be on IE8 - and since this browser is attacked the most, it's critical that you make sure it stays updated as needed. Firefox is the second most attacked browser, but fortunately, it has a self-updating feature built in. Google Chrome is also good because it has a self-updating feature as well as another security feature that runs plugins in "sandboxes," or restricted environments. If an attacker was able to exploit the browser and run malicious code, it would be isolated to this sandbox and would not able to effect the entire machine. Opera and Safari are also good browsers and should be kept current, too.
5. Keep Windows up-to-date: As always, Windows users should make sure their systems are current with the latest patches from Microsoft. Automatic updates should be turned on.
6. Keep Adobe Reader and Adobe Flash up-to-date: At the moment, Adobe Reader and Flash are the two most targeted programs by hackers. A lot of malware specifically goes after known vulnerabilities within Adobe's software. In addition, a common method of attack, such as that used by Koobface, is to redirect a victim to a malware-infested site where the user is prompted to update their Flash player or Adobe Reader in order to see the website content. NEVER do this. Always go to Adobe's site on your own to download the latest version or update the software on your computer using its own built-in update mechanisms.
7. Don't assume you're safe because you use a Mac: While it's true that Mac users are less targeted than Windows users, they are not immune to malware, despite what those commercials may say. Although Apple did include some malware protection in their latest operating system, it only protects users from two trojans; you cannot count on it alone to protect you. There are a couple of hundred of trojans currently in the wild that specifically target Mac machines, according to Kaspersky. In fact, there may even be as many as a thousand, but researchers are unable to identify all of them because Mac users don't typically run anti-virus software which is how much of the data is collected. These days, when a user clicks an infected link, the malicious web page will now sometimes identify whether that user is coming from a Windows or Mac machine and then display the appropriate version of the trojan accordingly. A particular family of trojans known as "DNS Changer" trojans are the most common ones used to attack Mac machines. The only way to really be sure that you're protected against these malicious programs is to run anti-malware software on your Mac, but most Mac users won't do so, preferring to take their chances since their risk is lower.
8. Be wary of email messages from social networks: Because email addresses can be "spoofed" by hackers, you can't assume that an email from Facebook or Twitter is really from those the site it claims to be from. As always, you should never open attachments you were not expecting to receive and you should be wary of clicking on links - especially if you're being told to "update your account." If you do click on a link and are taken to a web page that asks you to log into the site, DON'T DO IT. It would be handing over your password to the hackers. Instead, you should always access the sites directly by typing in their URL in your browser or clicking a saved link in your Favorites.

It's Not Just a Matter of Common Sense Anymore

As the above best practices show, a lot of the things you can do to protect yourself from malware are the same as they have been in the past - keep your computer and browser up-to-date, don't open attachments, etc. However, malware is trickier to identify these days thanks to social networking sites. It now uses the trusted identities of your friends in order to lull its victims into a false sense of safety. You can no longer simply assume that because someone you know posted a link, it's automatically safe. You can't even assume that the networks themselves are safe, either. They're not always scanned for malware-laden links, and when they are, such as is the case with Twitter, it's not a 100% effective method.

Security researchers are actively working on better ways to fight this problem - for example, Kaspersky just announced their "Krab Krawler" project which will help keep their blacklists current by scanning for malicious links on Twitter, but it's not a tool that end-users can download to protect themselves; it's only one of many methods that security firms use to collect data about the malware on the internet. The best way to stay safe is to follow through with all the best practices - not just one or two. Malware isn't ever going away, so everyone must do their own part in order to stay safe on the web.

Currently Brizzly is in private beta, but ReadWriteWeb has scored 2000 invites for our readers to test it out! (see the bottom of this post for the code).

Features, Including New Facebook Support

Brizzly is a self-described "social media reader." It's a browser-based service, like Blogger.com. Today Brizzly added Facebook as the second service it supports, after Twitter. Facebook users will be able to view and update their status, wall posts, comments and likes using Brizzly.

Brizzly is similar to Twitter clients such as TweetDeck, Seesmic and PeopleBrowsr (not all of them currently support Facebook though). However power users won't see much reason to switch, as Brizzly doesn't have the advanced features of those products. And that's the point.

The feature set of Brizzly aims to make microblogging a simple and seamless experience for users. For example instead of having to click links to view media such as photos and videos, Brizzly puts those items inline in the user's stream. Another example: Direct Messaging via Twitter has a UI (user interface) very similar to Instant Messaging, which many mainstream users will be familiar with.

Brizzly in 2009 = Blogger in 2003

Brizzly shares much of the same philosophy as Blogger. It's simple to use and aims to make microblogging easy to understand and use by a mainstream audience. This seems like a great strategy. Back in 2003, blogging was at a similar stage in its adoption as microblogging is today - passionately used by early Internet adopters, but not fully understood by a wider audience.

The popular Twitter clients circa 2009 include TweetDeck, Seesmic and PeopleBrowsr. Those are great apps and no self-respecting Web geek would be caught without at least one of them. However it's unlikely that your brother or sister, let alone Mom or Pop, is using those products. Brizzly wants to be the service that introduces your family and friends to the world of microblogging and social media.

Jason Shellen, who RWW readers may also recognize as a creator of Google Reader, was at The ReadWrite Real-Time Web Summit in October. Jolie O'Dell interviewed him about about filtration and discovery on the real-time web. Shellen mentioned that mainstream users probably won't use hashtags to tag their tweets. He noted (at about the 3 minute mark in the video) that "most people are not going to do that [hashtags], so it needs to evolve into a different type of filtration." One of Brizzly's goals is to make hashtags and other "geeky" social media concepts simple for mainstream users to understand.

Less Noise

Regular people often struggle to see the value in Twitter and other social media apps. Web app developers need to find ways to convince people that behind the noise of social media, there is tremendous value.

So how does Brizzly compare to the now Facebook-owned FriendFeed, an aggregation service that early adopters love but most others think is information overload? I spoke to Jason Shellen at the RWW Summit about that. He told me that Brizzly won't blend services together like FriendFeed. It will keep them separate (Twitter, Facebook, other services that are added over time), in order to maintain simplicity.

Conclusion

All in all, we're impressed by the vision of Brizzly and we think it has a good chance of hitting the same wide user base that Blogger.com so successfully tapped. It's fair to say that power users will probably be a little disappointed by Brizzly - but you're not the target audience.

The idea of a standalone Twitter handheld seems so far-fetched that we almost thought it was a joke - at least until we stumbled across this Amazon.com page listing the device for pre-order. Now the question is: who will buy this thing?

To some extent, we understand the appeal of the Peek handheld. Email is an essential part of doing business today but not everyone can afford a smartphone and the expensive monthly data plan required to use it. The Peek gives those sorts of penny-pinchers an alternative. For a one-time purchase price (starting at $19.99 on Amazon) and a reasonable monthly data fee of $15, Peek users are given a cheap way to read and respond to email on-the-go. Designed primarily for non-technical users, the Peek device is like a scaled-down Blackberry with less buttons, no microphone or speaker, no web browser or apps, and no scroll wheel - only a thumb wheel on the side. All it does is email, plain text email. No attachments, no formatting, no embedded graphics.

Despite its overly simplistic nature, the Peek makes sense. It connects people to their personal or, more likely, their business email accounts for an affordable price - and that's something that serves a real need in a down economy such as this.

...but Peek for Twitter?

However, the new TwitterPeek seems...well...sort of crazy, to be honest. Who's so addicted to Twitter that they're going to purchase this device instead of using Twitter's SMS service or just breaking down and buying a device capable of running apps or surfing the web? We know Twitter is a lot of fun, but is it really so essential that we need a standalone device?

At this point, the company would have almost been better off launching a Facebook handheld than a Twitter device. Twitter just hasn't achieved the sort of "must-have" status that would make people want something like this. We would bet that the majority of Americans wouldn't have even heard of the social network if it weren't for its adoption by celebrities like Oprah, Shaq, Ashton, Demi, and others or its heavily promoted use by news networks like CNN. Still, even though Twitter is no longer a foreign word to Americans' ears, that doesn't mean that the masses are actually using it. Oh don't get us wrong - they try. But earlier this year, Nielsen reported that more than 60% of Twitter's first time users abandon the service within a month of signing up. They just don't "get it" or see the need, they don't know how to find people to follow, and they certainly don't know how to get people to follow them back.

Yet it's this very demographic - the somewhat non-technical mainstream audience - that Peek exclusively markets their products to. These people can't even figure out how to properly use Twitter, but they're going to buy a standalone Twitter handheld? We don't think so.

Currently, Amazon lists two types of TwitterPeek devices: one with 6 months of service included for $99.95 or one with lifetime service for $199.95. The devices come in gray or a very Twitter-like aqua.
