The words of Seesmic's announcement make the company's rationale clear: the company is discontinuing support for Blackberry "in order to focus development efforts on our most popular mobile platforms: Android, iOS, and WIndows Phone 7."

Of course, this may just be one high-profile departure from that ecosystem, but there seems to be a sense that the RIM ship is sinking. At the same time, some analysts are predicting that Windows Phone 7 may see a large jump in adoption, and so focusing on that platform, along with Android and iOS would make sense.

The recommendations for Seesmic for Blackberry users, according to the company: "We encourage those effected by this change to try out Seesmic for Android, iOS, and Windows Phone 7." In other words, buy a new smartphone. Ouch.

Elgg is good for groups interested in creating niche networks under their own control, either publicly or privately. The service can run on your own servers or through a hosted version just launched last Summer. It came from the Education world and is used today by various organizations including Oxfam, Hill & Knowlton PR, the Australian government and the state of Ohio. Seesmic is a Salesforce-backed social network meta-service, allowing users to interact with multiple networks on multiple platforms.

Neither of Seesmic's leading competitors, Tweetdeck and Hootsuite, appear to support Elgg to date.

Leading social business analyst firm Altimeter published a research report last month about this sector of apps, which it calls social media management systems. That report identified 28 leading vendors. Altimeter's Jeremiah Owyang writes about the market:

"Social Media Management Systems... which help companies manage, maintain, and measure thousands of social media accounts, [and] are the next growth market for the social business category. While saturation is at 58% of corporate buyers, the average deal size is a meager $22,000 but will expect to grow to six figure annual deals in coming quarters to meet market demand.

White label social networks, like Elgg, are plentiful as well. ReadWriteWeb has done two in-depth interviews with Elgg co-founder David Tosh over the past 4 years. Tosh is now "experimenting" on a stealth project called Bluejac.

The new Seesmic Desktop - which went through a series of public beta tests - is a major update from the old version. As the company's founder and CEO Loic Le Meur told us earlier today, Twitter is still a major focus of the app - with native support for Twitter's streaming API, for example, and lots of Twitter-focused plugins in its library. You could also just use the app as a Facebook, LinkedIn, MySpace, Ning or Formspring client, however, and never even touch Twitter at all.

Seesmic Marketplace

At launch, the new Seesmic Marketplace will feature over 40 plugins. Over the last few months, the company's developer partners created plugins for a wide range of service, including ecommerce site Zappos, real-time search engines OneRiot and Topsy, as well as a Google Reader plugin and support for YouTube, Last.fm and Seesmic's own Ping.fm.

For now, all the plugins in the marketplace are available for free. Starting next year, Le Meur told us, Seesmic will also offer an e-commerce solution and allow developers to charge for their plugins.

Using Seesmic Desktop

We got a chance to test the final version Seesmic Desktop 2 ahead of today's launch. While the first beta versions had a number of quirks, this final version feels very polished and fast. Adding plugins is as easy as browsing the marketplace from your browser and hitting "install."

The only minor annoyance with installing plugins is that you have to restart the application before the plugins can be used. It is also a shame that the Twitter plugin does not show conversations, though it does offer virtually every other Twitter feature you would expect to find in a modern desktop client.

The layout of the app, with side tabs for 'searches,' 'userlists' and 'accounts' still harkens back to Seesmic Desktop's Twitter legacy. Once you install a lot of plugins, this static and Twitter-centric list of tabs quickly feels limiting. This won't be a problem for long, though, Le Meur told us, as the team is already working on a more flexible tab layout. Thanks to this, you will soon be able to keep all your news-related Twitter lists and plugins in one tab and all your personal Twitter lists and your Facebook stream in another, for example.

Overall, these are just minor issues. After using Seesmic for a while, the application's potential to become a major desktop hub for real-time services quickly becomes clear and hopefully, more developers will soon offer plugins for their services as well.

"After many presentations on social networking around the World, I found myself getting the same questions all the time so I decided to share everything I learned in a series of 30 HD videos," writes Le Meur on his personal blog. "They aren't aimed at experts but rather anyone who would like to learn from scratch how to make the best from social networking and building their brand."

The video series itself serves as an example of how social media has transformed the way we market ourselves and our companies on the Web. Le Meur could have simply blogged these ideas in a few lengthy posts, but instead he's being more interactive and providing a richer personal experience by creating a daily video series.

Companies and professionals can do this too, so check out Le Meur's video series for what should be a fun month of branding tips!

"A blog post can automatically go to up to 50 social networks," said Loic Le Meur, CEO of Ping.fm's corporate overlords, Seesmic.

This new feature is a real-time feed effected by Superfeedr, a service that transforms a wide variety of feeds into normalized XMPP or Pubsubhubbub format.

Currently this feature, which is powered by Superfeedr, only carries a single feed but Le Meur said the company is working on expanding it to allow multiple feeds within a couple of weeks.

"We are testing with (just) one right now," he told us. "We will add several soon after we scale one. Ping.fm has 700,000 users so (are being) careful!"

With this new version, Seesmic Web continues to blur the line between desktop and web-based Twitter clients.

The nicest new feature in Seesmic Web is the ability to drag and drop contacts to any list. Compared to TweetDeck and other desktop tools, this makes managing and creating lists a lot easier and makes for a more efficient workflow.

Contact Manager

Another interesting new feature is the contact manager, which allows you to quickly get information about your followers. The contact manager displays the basic information from the user's profile: number of followers and tweets, favorite tweets and information about the lists this user follows. In addition, Seesmic also displays the names of this user's top 3 most publicly contacted friends on Twitter.

Better Integration with Third-Party Tools

One area the Seesmic team has focused on for this release is the integration of third-party tools. A small icon appears next to every shortened link now and clicking on this link will bring up some basic information about the link, including the name of the site the link will take you to and the number of retweets (powered by Tweetmeme).

Seesmic Web now also allows users to share pictures from the web interface and also offers picture previews right inside the app for pictures that were shared on most of the popular Twitter photo services.

Geolocation

As long as you use a browser that supports Google Gears, Seesmic Web now also makes it easier to share your location. Whenever you write a new tweet, you can choose to attach your location to this message. Just make sure you have the location feature turned on in your Twitter settings. As we reported last month, only a very small number of Twitter users currently makes use of this feature, which isn't a surprise, given that only a handful of Twitter apps currently support this functionality. It's good to see that Seesmic is making this feature a priority in its apps.

Verdict

Overall, the experience of using Seesmic Web comes very close to using a desktop client. There are a few features that are still missing in the web version (resizable columns, for example), but otherwise, Seesmic Web is a very good replacement for a desktop Twitter client.

Using a web-based client brings a number of advantages with it, including the absence of any Twitter rate limits. If you like the Seesmic interface give it a try in a site-specific browser like Fluid on the Mac or Mozilla's Prism.

By default, Seesmic now loads new tweets on top of the older ones (just like Tweetie on the iPhone). A lot of users prefer this system of loading new tweets, but if you would rather see Seesmic jump straight to the top of your new tweets, you can switch this feature off in the settings menu.

According to Seesmic, support for multiple accounts was one of the most often requested features. Thanks to the app's support for multiple accounts, you can now also easily post the same message to multiple accounts simultaneously.

Another new feature in Seesmic for Android is support auto-correction and auto-capitalization in the composer.

But What About the iPhone?

Seesmic was already the best Twitter app on Android and this new release just takes it one step further. According to Seesmic's founder and CEO Loic Le Meur, over 100,000 people have already downloaded the app. We tested Seesmic for Android on a Nexus One and it's worth noting that the new version of the app feels even more responsive than the first release.

Given how well Seesmic for Android works, we can only hope that Seesmic will soon release an iPhone app (the company already offers a BlackBerry app). The last time we talked to Le Meur, however, he told us that the company wants to be able to offer something special and not just look like a "me-too" player on the iPhone, so it might still be a while before we get to see Seesmic on the iPhone.

As Seesmic's founder and CEO Loic Le Meur told us yesterday, there hasn't really been a lot of innovation in the Twitter ecosystem when it comes to Twitter clients. Seesmic Look is squarely aimed at mainstream users. Instead of giving users lots of options, it tries to keep things simple. Users, for example, don't have to decide which users they want to follow. Instead, Seesmic has created an interactive experience that is more like browsing TV channels than using a traditional Twitter client. Seesmic Look offers a curated list of Twitter accounts that are organized by interests like news, sports or celebrities.

These curated channels are hosted on Seesmic's servers and Seesmic plans to regularly update these lists

Seesmic collaborated with Microsoft on this product and conducted extensive usability testing to make sure that the software is easy to use. The application was optimized for Windows 7 but will work on any modern Windows operating system.

Emphasis on Design and Usability

Seesmic clearly devoted a lot of time to getting the design of the app right and the screenshots don't really do it justice. Depending on the mode (timeline or playback), tweets fade in and out and scroll across the screen, for example. The background of the app changes continuously and matches the Twitter background of the user or brand you are looking at. Seesmic also supplies two built-in themes: one light and one dark theme. More themes will follow in the future.

Not for Power Users

It's important to note that Seesmic is intentionally not targeting power users with this application. This does not mean that the app isn't also a fully featured Twitter client. Users don't need a Twitter account to browse through Seesmic Look's channels. If they do sign in, however, they can browse their inbox (direct messages and @replies) and their personal Twitter stream. The app also supports lists, and Twitter search and trends are prominently featured in the user interface.

For now, new users can't set up a new Twitter account in the application, but Seesmic is working together with Twitter to make this possible in a future version.

Seesmic Look for Brands

In addition to the Seesmic-curated channels, Seesmic Looks will also give brands the option to showcase their Twitter accounts in branded channels. Among the eight launch partners Seesmic announced today are Red Bull, the Huffington Post, Kodak, CNN Money and Ford. Le Meur told us that these companies are currently getting free exposure during the launch phase. Seesmic plans to charge monthly fees for these channels in a few month. Brands will also be able to create their own themes and distribute branded versions of Seesmic Look in the future.

For Seesmic, this represents an obvious opportunity to create a revenue channel. To get these brands into the app, Twitter has partnered with Microsoft, which was responsible for bringing roughly half of today's launch partners to Seesmic.

As Le Meur told us, Twitter itself is also quite excited about the prospects of this app and has given it its official seal of approval.

This is definitely an interesting strategy for Seesmic. Brands obviously want to use Twitter to connect to mainstream users. For a lot of new users, however, understanding Twitter is simply too complicated. Twitter has always struggled to convert new users into regular users, which explains why the company would be so interested in supporting this project.

Hours after high-profile Silicon Valley social aggregation service Seesmic announced that it acquired angel-backed cross-network publishing service Ping.fm, a similar deal was announced in Europe. Identity management service Critical Path, maker of software called Memova, announced that it has acquired mobile uploading service ShoZu, a company that had received an enormous amount of venture capital.

ShoZu raised more than $30 million to build a mobile app that allows users to publish photos, videos and text to more than 50 different destination social networks like Facebook, Twitter, Flickr, Blip.tv and more. The service has long been popular on Nokia phones and sells an iPhone app for $5. Shozu was voted one of our readers' favorite mobile apps in 2007. For more about ShoZu see this Techcraver interview with the company's CEO.

Critical Path is a little like a combination of Plaxo and Verisign. It offers messaging and social apps, APIs, Identity Management and Access Control.

Was this the big exit that ShoZu's investors sought? Almost definitely not. Critical Path is an innovative service that's got some big customers like BT, France Telecom and Orange, but it's unlikely that ShoZu came at a high price. Spence alludes to the same when he writes that Critical Path "saw the potential of combining their Memova platform suite with ShoZu's engineering." Update: In the official release, ShoZu Board Director Nigel Pilkington from lead investor SEB Venture Capital UK, called the deal "a successful outcome for us." Maybe that's being polite, maybe it's true or maybe it was a small success financially.

It's most likely a talent deal and evidence that cross-platform publishing tools like ShoZu, Ping.fm and competitor Pixel Pipe are probably not stand-alone businesses. Just like FriendFeed's aggregation across scores of APIs wasn't enough to make it a success outside of being scooped up by the much, much larger Facebook - these other companies that create the pipes for the tubes just aren't compelling enough to a large number of consumers.

They do make nice acquisition targets, though, and show that the future of the social web may not be found in reading and writing to one single network like Twitter or Facebook. The savvy companies that are building value on top of those networks are also dedicating resources to bring on engineers skilled at working with far more networks to publish to or read from.

Twitter's Director of Platform Ryan Sarver followed up on earlier public announcements this weekend with an email to developers explaining plans to raise the limit on the number of times an application can request information from Twitter for a single user to 10 times what it is today (from 150 req/hr to 1500/hr), and to offer everyone the same kind of paid access to the full "fire hose" of user updates that Google and Bing enjoy. People who build cool Twitter apps say this is very big news.

Twitter developers say the new changes could lead to:

• Richer functionality for apps and services, beyond new user interfaces.
• More development around new features like retweets and Lists.
• More real-time user experiences.
• Improved viability for the Twitter API.

We spoke to some of our favorite developers about both the API limit increase and the fire hose access. Here's what they had to say.

Iain Dodsworth, Tweetdeck

"Not wishing to overstate the case but these changes will allow for the next generation of Twitter app. So far the ecosystem has mainly concentrated on providing numerous new UIs onto Twitter (with pretty good success I might add). Potentially the 10x API will signal a shift towards richer functionality & service development: Twitter 2.0. [emphasis added]

"We're already working on functionality which mines and analyses Twitter data within the application layer which wouldn't be possible without a 10x API limit. I'm interested to see how the API scales with these new API limits."

Loic Le Meur, Seesmic

"The increased API limits allow apps to come up with new interaction models for Twitter, and also to catch up on all the new features Twitter added (new RTs, lists), which couldn't be supported properly with 150 requests per hour. "

Justyn Howard, SproutSocial

"On the 10x increase - Not too many people bump into the authorized limit today unless they run multiple apps, but that was by design. All of us developers built in controls to limit the calls, which has left power users constantly slamming the refresh button. So this does a couple of things: 1. It allows developers to loosen the logic throttling API calls which will create a closer to real-time experience for the end-users. 2. Also opens some new opportunities on cool things we can do which require the user API vs. Search (some things you can't get from the open API's, you need to use the user's account to do them). 3. Will open the doors for more secondary apps, where users previously couldn't have more than one or two [different Twitter apps] open without hitting rate limits, you'll see more people using niche apps in the background if they provide some capability beyond what Seesmic, Tweetie and Tweetdeck offer."

On Access to the Firehose for Everyone

Kevin Marshall, co-founder of innovative social graph parsing application provider Wow.ly, builds apps that have a clear need for increased rate limits. "This is great," he told us, "because the 150 per hour limit in conjunction with various API features (for example, the social graph API) makes it very difficult to pull off some more 'advanced' features I would like to build."

On offering the Firehose to everyone, Marshall had an unusual and interesting response that demonstrates the maturity that this ecosystem is developing. It's not a simple matter of everyone chasing thoughtlessly after the real-time stream.

"The more I do with and around social data, the less interested I seem to become in 'realtime' and the more interested I become in 'over time.' When I first started hacking on Twitter (and Facebook) apps, I was in love with the idea of parsing and analyzing data in real-time and I was very link/content focused. But the more I build and use these tools, the more I see the value in the history and the trails of the data set - especially when you consider that we are all living in a more asynchronous world then ever before thanks to things like blogs, Tivo, Hulu, iTunes, and other media-on-demand stuff. I don't think it's really so much about 'what are you doing right now' as it is 'what have you done that's interesting to me right now?'...and I think you get that by aggregating and analyzing."

None the less, many developers will welcome the opening of previously selective fire hose access. Mailana founder Pete Warden says even his seed-funded company is looking forward to ponying up some cash.

"This may sound counter-intuitive as a starving entrepreneur," he told us, "but the best guarantee the API will stay open and available is if Twitter makes money from it."

"It gives developers the chance to move from being charity-cases to paying customers, and so gives Twitter a lot more reasons to listen to what we want. Anyone who wants to deal with the flood of data from the firehose already has to invest in some beefy hardware, (my server and bandwidth bills are thousands of dollars a month) so reasonable fees from Twitter shouldn't raise the barrier to entry by much."

These changes are expected to go live soon and we look forward to seeing what they enable new and old Twitter apps to do.

You can find and follow the RWW team on Twitter here.

All of this added functionality could have cluttered up TweetDeck's interface, but the team decided to redesign parts of the interface. A single '+' button at the top of the app now opens up a new dialog that allows you to add lists and Facebook, MySpace and LinkedIn columns to your view. From there, you can also start new Twitter lists.

TweetDeck's Ian Dodsworth also told us that TweetDeck will soon be able to show its users composite profiles of TweetDeck users based on the social network profiles they have added to TweetDeck.

Auto-Updated Lists

As Twitter still restricts the number of calls a user can make to the Twitter API, TweetDeck's competitor Seesmic decided to have users update lists manually. In TweetDeck, lists will update automatically and you can set the frequency of these updates in the app's settings dialog.

TweetDeck also makes it easy to start new lists from existing lists, which is great if you want to extend somebody else's list with your own picks, for example. TweetDeck will also suggest users for a list. We are not quite sure how TweetDeck makes these suggestions, but they seem to be based on the title of your group.

You can find a full lists of all the tweaks and new features in TweetDeck 0.32 here.

Battle of the Twitter Clients

The auto-updating lists currently give TweetDeck a slight lead over Seesmic, which introduced lists as a core feature of its desktop client a few weeks ago. Seesmic's new Seesmic for Windows, however, can now be extended with Firefox-like plugins. Because of this, Seesmic can now farm out a lot of development to third-party developers, and anybody can create a column for LinkedIn or any other social network.

According to social media monitoring service Sysomos, TweetDeck is currently the single most popular Twitter client after Twitter's own website. It took TweetDeck a while to release today's updates and the company surely lost some users to Seesmic in the meantime. This new update brings TweetDeck back on par with the competition, and even adds a number of new features — like the ability to clone lists — that its competitors don't offer (yet).

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.

Here are the latest tools and services we've come to love, maybe you'd like to give them a try too.

Topify

Ever feel frustrated by the emails you get from Twitter? We did, until we signed up for Topify. From really smart "X is now following you" emails to the ability to reply to direct messages by email - Topify delivers Twitter emails like Twitter ought to. It's another project from Ouriel Ohayon, who's also behind the wonderful iPhone app sharing service AppsFire. Ouriel makes cool stuff.

Seesmic Web

The never-ending battle between Seesmic and Tweetdeck to see who can make the coolest Twitter client is great for users. Tweetdeck ate my groups last night in an upgrade, after I'd spent hours building them, and so I decided to give Seesmic another try. The Seesmic Web app is awesome and Mac users can turn it into its own app on the desktop using Fluid. The best of many cool features? List support! You can turn any list you're following on Twitter into its own column in Seesmic. Frederic Lardinois says he's been using this combo for a few weeks, I still have some kinks to work out.

Tweetie 2

The iPhone app Tweetie (iTunes link) made a major upgrade last month and we're loving it. Sarah Perez put this one on the list but everyone agrees - this is hot stuff. Will the forthcoming Seesmic Mobile app be as good? Will Tweetdeck's eventual support for Twitter lists turn into an awesome iPhone app? We'll see - but Tweetie's many rich features make it the app to beat right now. My favorite feature? The way the replies page can be pulled down like a spring to prompt a refresh. It's a little thing, but it's fun.

Aardvark

Aardvark leverages what it calls "the real-time web of people" to deliver answers to any question you have - from people in your social circle who know about the topic and are available at that very moment. Vark gets mixed reviews from some people, but I love it. From technical questions to practical ones about life to opinions about questions I have at work - I've been getting a lot of fast, helpful information from people on Aardvark lately. It's another app that scores very high on User Experience, especially in its iPhone and IM interfaces.

Chrome/Chromium

Google's web browser is fast, it's really fast. It's hard to say goodbye to all the wonderful Firefox extensions we've been using for years - but it's harder to use any other browser once you've been using Chrome for awhile. We have high hopes for Chrome plug-ins, but even without them it's a joy to use. You can download Chrome for Windows here and Chromium for Mac here.

LazyFeed

LazyFeed is a topic-driven "discovery engine." It's basically a blog search client that brings in the freshest posts about topics you're interested in. A couple of months into using it, I'm still finding great content every time I fire it up. I've got this running in Fluid and it works great.

Want some serendipity on the iPhone? Try out competitor YourVersion's app. The first version isn't easy on the eyes, but it delivers roughly the same experience on the go.

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.
