Of course, a number of publications picked up on this, suspecting it was a hint about today's news. But last night, the tweet in question disappeared...which actually seems more of a confirmation that the original tweet ever did.

But the source of the tweet was interesting: "Twitter for iPhone." Was this a sneaky, subtle hint about today's news? Or was the person in charge of the Verizon Twitter account actually using an AT&T iPhone?

But what was even more strange is that the tweet getting copied and reposted around the Web oddly disappeared only hours later. Did Verizon pull it down? Apparently. And a Verizon PR isn't saying why.

I think we know.

Google still has the tweet in its cache here.

@VerizonWireless, Such a Tease

In the meantime, if you're looking for interesting tweets, @VerizonWireless has been a tease for days, tweeting yesterday: "Getting ready to make news on Tuesday," and now this morning asking a follower "if we said what the Verizon event Tuesday is going to be about - would it still be news?"

Yes, yes it would.

But what can be done? It's not like you can just quit Facebook, right? No - and you don't have to either. You just need to take a few precautions.

The problem in implementing these privacy options is that they're just too confusing for most non-tech savvy people to handle. And often, folks don't want to bother to take the time to learn. To simplify the process, we're offering five easy steps you can take today to help make your Facebook experience safer, more secure, and more private.

Step 1: Make Friend Lists

Yes, it will take some time, especially if you're connected to a couple hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.

Friend lists, like they sound, are lists for categorizing your friends into various groups. The nice thing about this feature is that once you set these lists up, you won't have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list designated "work," personal friends you're not very close with into a list called "Acquaintances," and people you're related to into a list called "Family." Those three main categories will separate out the groups of "friends" who you may want to hide some information from.

To create a friend list, click on "Friends" at the top of the Facebook homepage. In the left-hand column, click "Friends" again under the "Lists" section. Now you'll see a button at the top that says "Create New List". Click it. In the pop-up that appears, you can name your list and pick members. If you've ever shared an application with your friends, the process of doing this will be very familiar.

When you've finished making lists, you'll be able to use them when selecting who can see what (or who can't!) when configuring the security settings described below.

Step 2: Who Can See What on Your Profile

At the top right of Facebook, there's a menu that many people probably ignore: "Settings." But this menu is now going to become your best friend. To get started, hover your mouse over the Settings menu and click "Privacy Settings" from the list that appears. On the next page, click "Profile." This takes you to a page where you can configure who gets to see certain information on your profile.

Before making changes, think carefully about the sorts of things you want public and the things you want private. Should "everyone" get to see photos you're tagged in? Or would you like to limit this only to those you've specifically chosen as Facebook friends?

Underneath each section on this page (basic info, personal info, status, etc.), you can designate who gets to see that particular bit of information. For anyone not using custom lists (see step 1), the best thing to enter here is "Only Friends." Anything else opens up your profile information to people you may or may not know. For example, choosing "Everyone" makes that info public, "Friends of Friends" lets your friends' friends see it, "My Networks and Friends" opens up your info to anyone in your networks - that means anyone in your city, your high school, your college, a professional organization you listed, etc.

You can also block certain groups from seeing these sections, too. On any item that offers an "Edit Custom Settings" option, you can click that link to display a pop-up box where you can choose people or lists to block (see where it says "Except these people"). If you haven't made custom lists as explained in step 1 above, you can enter individual names here instead. (Sorry, mom, dad, boss - this is where you get blocked.)

Step 3: Who Can See Your Address and Phone Number

Did you list your address and phone number on Facebook? While that's a handy feature, you may not want everyone you friended to have this information. To access this configuration page, you follow the same steps as above in step 2 to display the Profile Privacy page. You'll notice that the page has two tabs at the top - click on the one that reads "Contact information."

As previously described above, you can again use the drop-down lists provided to designate who gets to see what and/or block certain people or lists from viewing this information. The sections on this page include "IM Screen Name," "Mobile Phone," "Other Phone," "Current Address," "Website," and your email.

Step 4: Change Who Can Find You on Facebook via Search

Sick of getting friend requests from old high school pals? While for some the beauty of Facebook is that it lets you reconnect with everyone you ever knew throughout your life, others find this intrusive and annoying. You're not friends with any of these people anymore for a reason, right?

As it turns out, you can still enjoy Facebook without some folks ever knowing or finding you thanks to the search privacy settings.

Click on the "Settings" menu on Facebook's homepage and then click "Search" on the following page. You'll be taken to a Search Privacy page where you can specify who gets to find you on Facebook. Want to be wide open? Change the "Search Visibility" drop-down box to "Everyone." Want to keep it a little more limited? Select "My Networks and Friends," "Friends of Friends," or "My Networks and Friends of Friends" instead. Don't want anyone finding you on Facebook? Change it to "Only Friends." That means only the people who you've already friended can find you in a Facebook search.

On this page, you can also configure what information displays when your info is returned as a search result (e.g. your profile picture, your friend list, etc.). In addition, you can check and uncheck the boxes for network-based searches too. For example, if you don't want anyone from high school to find you, uncheck the box next to "people in high school networks."

Step 5: Stop Sharing Personal Info with Unknown Applications

Remember when we told you about what Facebook quizzes know about you? Using Facebook's default settings, you're unknowingly sharing a plethora of personal information (and your friends' info too!) with various Facebook applications and the developers who created them. The problem is so bad that the ACLU recently created their own Facebook Quiz to demonstrate how much information an app has access to.

It's time to take back control! From the Facebook homepage, hover your mouse over the "Settings" menu and choose "Privacy Settings" from the drop-down list. On the next page, click "Applications" then click the tab that reads "Settings" which is next to the "Overview" tab. (Oh, and if you want to really be freaked out, read that overview!)

On this page, you can check and uncheck boxes next to your personal information (picture, education history, wall, religious views, etc.). This controls what the applications your friends are using can see about you. Yes, your friends' apps can see your personal info if you don't make this change! Believe it or not, you don't have the same control over your own apps. The best you can do is head over to the Applications page and delete the apps you're not using anymore. (Use the "X" to remove them.) You see, once you authorize an application, you're telling it that it's OK to access any information associated with your account that it requires to work. While some developers may only pull what's actually required, many others just pull in everything they can. Scary, isn't it?

Conclusion

While this is by no means a comprehensive guide to Facebook security and privacy, these five steps can help you get started in creating a safer, more secure, and more private environment on the social network.

However, if you choose not to take any precautions, then you'll only have yourself to blame when an errant wall post or naughty photo makes its way online and straight into Grandma's News Feed, or worse, your boss's. These days, it's better to be safe than sorry, so go ahead and delve into those settings!

Unfortunately, there seemed to be a problem with the new security feature: it wasn't working...or at least, so it seemed. As it turns out, the problem was that users weren't informed as to how to properly activate the anti-phishing protection, an issue that points to a poor implementation of what could and should have been a major breakthrough in mobile computing technology.

Although Apple touted the anti-phishing protection back in March when they announced their 3.0 update, the new feature didn't actually materialize until this month when the company released the OS 3.1 iPhone/iPod Touch software. According to Apple, the anti-phishing protection feature will display an on-screen warning message when you attempt to visit a known malicious website.

Once the update was released, security researchers and other Apple enthusiasts began testing the new technology. The results were immediately disappointing. "I've not been able to get it to block anything," Michael Sutton, vice president of research at security firm Zscaler was quoted as saying. He had been testing the feature using known phishing websites identified by the anti-phishing database hosted at PhishTank. The Mac Security Blog also found after extensive testing that it simply "does not seem to work." MacWorld, however, found that the feature worked sometimes, but the inconsistency hinted that the technology was not "ready for public consumption," they reported.

What gives? Did Apple really release a broken feature? Were they even aware of the problem? Blogger Jim Dalrymple of The Loop decided to go straight to the source: he asked Apple.

Apple Says "You're Doing it Wrong"

Apparently, this was not a case of the anti-phishing technology being broken. It was a case of everyone simply "doing it wrong." As it turns out, in order for Safari's anti-phishing database to update, there are a few particular steps that need to be followed, explained an Apple spokesperson. After updating the phone to the OS 3.1 update, users need to do the following:

1. Launch the Safari web browser.
2. Connect to a Wi-Fi network.
3. Charge the iPhone with the screen off.

The spokesperson added that for "most users" this process should happen automatically when they charge their phone. We would have to disagree. "Most users" don't launch the Safari browser prior to charging their device - if anything, they close down any open applications before plugging in the phone to charge.

Poorly Implemented, Poorly Explained

If you follow the above steps, the feature will work. However, most users will never know to do this unless they happen to closely follow technology news and blogs. The general mainstream population - the very demographic Apple so craftily attracts via their billion dollar marketing campaigns - expects things to "just work." That is the Apple promise, after all.

Yet even on Apple's own website where they detail the various new features in the OS 3.1 update, there is no mention as to how the anti-phishing protection should be utilized. It simply lists that the feature exists. A helpful link to a "how to" guide would seem appropriate here or, at the very least, a footnote.

Having to perform the somewhat unintuitive steps to get the anti-phishing protection feature to function properly seems like an unusual miss for a company who generally makes things simple and straightforward. Why does it need Wi-Fi, for example? Apple claims that the Wi-Fi connectivity is required so as not to incur any additional data fees for the end user. But launching the browser? We almost wonder if it wouldn't have made better sense for Apple to implement the feature in the new iTunes update instead. The desktop software could retrieve the updated anti-phishing database from the internet upon launch and could then sync it to the iPhone or iPod Touch the next time it was plugged in. That would also alleviate another common problem with the current implementation - if the phone isn't plugged in long enough, the update won't complete and users will only be partially protected. On the other hand, the inclusion of the database via a sync would have ensured that all the data was copied over to the phone.

In the end, though, Graham Cluley, a senior technology consultant at Sophos, reminds us that maybe we shouldn't be too hard on Apple. "Many other smartphones don't offer even the most elementary form of anti-phishing protection to their users," he says. That may be true but, unfortunately, the way Apple chose to deliver their anti-phishing protection feature means that most iPhone users won't be protected either.

Is it doing any good? Do our efforts, symbolic or concrete, have any impact? We don't really know. Critics will point out that, for the most part, people are jumping on a bandwagon. Very few of us have any real grasp of Iran's political or social complexities; we have no idea who the leading opposition candidate is or what kind of record he has (and most of us would recoil if we found out). All true.

What we do have, though, is a shared belief in human dignity, and a shared recognition that this is a chance for that cause to take a big step forward. Green avatars are, in a sense, a way of signaling as much to each other: "Yeah, I care about this, too." Perhaps we do this to show solidarity as much with each other as with the people of Iran.

More Noise to Signal.

Three Keywords - Three Languages

In its current state, Monitter is restricted to always displaying three keyword searches in three separate columns. Once you change the keywords, Monitter will display the last tweet with those keywords in it and then constantly update the search. In our tests, it never took more than 30 seconds before Monitter picked up on a new tweet.

One of the really cool features of Monitter is that you can filer tweets by language. Right now, those languages are English, Spanish, and German. Overall, those filters seemed to work very well. This does, however, also mean that you won't see tweet in other languages, which is a bit of a limitation, but will probably only bother very few users.

As the folks over at Web Worker Daily point out, Monitter also works great in a site specific browser like Fluid on the Mac or Bubbles on the PC.

Widget

The Monitter team has also built an embeddable widget so that you can display these searches on your own site. Because of how wide the widget has to be, though, this approach might not be really useful for a lot of people.

Competition

There are, of course, various Twitter search engines available already. Summize, which was bought by Twitter and is now the standard Twitter search engine, is great way to search for specific keywords and allows you to reply to tweets right from the application. Twitscoop, which we reviewed about a month ago, is also a very capable Twitter search engine and features a very cool, constantly updating tag cloud.

Verdict

In terms of its features, one nice addition to Monitter would be the ability to reply to tweets right out of the application. Even more interesting would be the ability to send tweets right out of the app, which would, of course, make it even more of a TweetDeck for the browser (an inspiration that, by the way, the developer fully acknowledges). Also, it would be nice if you could turn off the language filtering.

Overall, though, Monitter is a cool and well designed way to monitor certain keywords on Twitter. It is not so much useful as a search engine, as it only displays the last tweet that matches your keywords. Its power is in constantly updating these search results, and while its competitors can do this as well, Monitter's ability to track more than one search is often very useful. If you already use TweetDeck, this application might not be too useful for you. However, if you are using Twhirl or any other Twitter client, then you could do a lot worse than giving Monitter a try.

The idea of using a tag cloud to track memes on Twitter is obviously not new, but having the tag cloud update dynamically makes for a whole new experience. While testing Twitscoop this morning, for example, the news about Carl Icahn's newest letter to Yahoo's shareholders was breaking on Twitter and made it onto Twitscoop's tag cloud within less than a minute.

Sometimes, the items on the tag cloud seem to appear more because of serendipity than because they are real memes. If five people write the 'dumb' or 'w00t' within 10 minutes of each other, for example, it will show up in the cloud, even though the tweets are not related at all.

If a tag cloud seems especially noteworthy, you can easily send a tweet with a permalink to the cloud. While this might only be useful in a very limited number of occasions, it is a nice feature to have nevertheless.

As of now, Twitscoop does not feature an API, nor does it have a widget for its live tag cloud that you could put on your blog or your desktop.

Search

Twitscoop is also a very capable Twitter search engine. While it is pretty basic, in that it doesn't feature live updates like Summize, or organize conversations like Quotably, it does show a nice graph of how often a search term has been used on Twitter in the last 6 to 72 hours (see screenshot). Just like on Summize, you can reply to a tweet from the search page and there is a link to the original tweet as well.

Twitscoop picks up new tweets very fast - most appear in under one minute.

Verdict

The ideal Twitter search engine would combine the live updates and API from Summize, the live tag cloud from Twitscoop, and the conversation tracking from Quotably. As of now, we still have to wait for this, but Twitscoop's live updates are definitely worth taking a closer look at and its search engine is a good alternative to Summize.

TweetDeck is an AIR based application that was first discovered by Louis Gray. The major difference between TweetDeck and other Twitter clients like Twhirl, Snitter, Twitteriffic, and AlertThingy, is that it displays more than one column of information at a time. In TweetDeck, you can define columns for your replies, numerous searches in Summize, as well as groups. You can define up to 10 different columns.

The developers seem keenly aware of Twitter's problems and provide you with a status message at the bottom right of the client. We have seen it alternate between "Pretty much okay" and "Rate limit exceeded'" today. There is also an indication for when the last tweets were received in the bottom left corner of the application.

Columns

The column display can be rearranged according to taste - only the "All Tweets" column is fixed on the left side. Having all these columns open at the same time obviously means that TweetDeck occupies a lot more screen estate than other Twitter clients - however, the amount of information displayed is far greater as well. For some, this is a trade-off worth making, while it might be a deal-breaker for others.

Groups

The groups function is very useful, especially for people who follow a lot of people, but still want to be able to quickly see what their closest friends (or competitors) are saying. Usually, these messages are easily drowned out in the mass of tweets that come in at any given time.

Once a group is created, you can make changes to it by clicking on its name.

Right now, when you create a group, TweetDeck doesn't display a list of all your friends right away. As TweetDeck becomes aware of more of your friends over time, this problem disappears as TweetDeck's internal database picks up on your friends, but this might be quite confusing and frustrating for first time users.

Preferences

One area where TweetDeck could use some more work is in its preferences - right now, there pretty much are none. You can't change the speed by which it checks for new tweets, there are no themes to chose from (why, by the way, do all AIR apps have to be so dark?), and there is no way to change the size of the fonts.

Verdict

TweetDeck is probably not for everyone, but especially with Twitter's track function still being offline for now, the ability to have a persistent Summize search right in the client is a great feature just by itself. Once the group function works a little bit better, I would venture to guess that a lot more people will start using it. But even in its current state, it is definitely worth a closer look.

Most strikingly, we found that a whopping 5% of all Twitter (in terms of tweets) is powered by the top 100 active accounts. Those 100 users post updates 200-3000 times a day, which might even impress uber-Twitter users like Robert Scoble or Jason Calacanis.

What we saw was that the top Twitter users are not always people, but rather, they're sources using Twitter as a feed publishing platform. For example, the most active user we saw was an account called "lejddfr," which does "push journalism" (sending out frequent links to new stories) for French news service Le Journal du Dimanche. lejddfr has just 315 followers, is following no one, and has made over 101,000 tweets. Another example we saw is "GSSP," which tweets links to stories on the news web site NewzOf.com. Our favorite high volume Twitter user, though is "chandraxray," a space station that tweets its location up to 350 times per day.

To get a feel for the distribution of tweeting activity across the Twitter universe, we sorted users by the number of tweets per day and graphed that vs. the total traffic. 66% of the users only tweet once per day.

But that still doesn't answer the question of what people are talking about. So we started analyzing tweets and came up with a list of the top five words people send. Apparently, the first thing anyone sends out on Twitter is a "test" message.

1. test
2. lol
3. working
4. :)
5. sleeping

Unfortunately, while we can guess from that list that Twitter users tend to be sleepy workaholics who are generally happy, we still can't tell much about what they're really talking about on the service. So we next applied some fancy topic extraction and started calculating trends over our week's worth of data.

What we found is that there are three main types of conversations going on. First, there are status updates of every day occurrences such as, "getting coffee," "check out this post on X," "going to sleep," or other mundane life things. Second, there are short term memes where many people talk about some event before, during, or after it. These conversations are usually short lived -- ranging from a few minutes to a few hours. For example a TV show like "Lost" will have some buzz, before, during, and for a short time after the show airs, but will drop out of the stream very quickly. We saw that happen with "LSD" when the drug's creator Albert Hoffman died last week. The final type of discussion we see on Twitter, are long term memes. These are topics of interest that people talk about for days, weeks, or even months. Politics or new video games are great examples of these longer term discussions happening on the platform.

Below we selected a subset of the automatic trends found for the week to illustrate this phenomenon. Each column from left to right shows the days of the week. Topics on the top of each stack represent shorter lived memes, while topics lower on the chart represent items of longer term interest.

You can click on the links below to explore the memes on those days:

Sunday, April 27: Obama, GTA IV, Mario Kart Wii, Coachella, Facebook, NFL, BBQ, Ubuntu, Spurs
Monday, April 28: Obama, GTA IV, Mario Kart Wii, Coachella, Rev Wright, iMacs, Facebook, Social Brew
Tuesday, April 29: Obama, GTA IV, Iron Man, Rev Wright, Ben Jerry, Celtics, Lakers, Deal or No Deal
Wednesday, April 30: Obama, GTA IV, Iron Man, American Idol, LSD, iGoogle, Violet Hill, Neil Diamond, Spurs
Thursday, May 1: Obama, GTA IV, Iron Man, RSS Awareness Day, Diggnation, Baskin Robbins
Friday, May 2: Obama, GTA IV, Iron Man, DC Madam, Hawks, BSG, Lost
Saturday, May 3: Obama, GTA IV, Iron Man, Kentucky Derby, Free Comic Book Day, Maker Faire, YouTube, Boris

Conclusion

While technology, politics, and geekery (sci-fi movies and video games) tend to dominate the long term memes, people are discussing all sorts of things on Twitter -- from sports to pop culture to cooking. Could that indicate that the site it starting to have some mainstream appeal? Or maybe just that even us tech geeks occasionally find time to talk about things other than technology? Either way, the way memes flow on Twitter is an interesting topic and one that we had fun looking at.
