Adobe AIR-based microblogging client Twhirl already supported Twitter, Friendfeed and Seesmic, and now its coverage of the world of mini-updates gets even broader with the addition of Identi.ca. Identi.ca is something like a less-popular open-source version of Twitter. This is a big deal for the Identi.ca folks, because Twhirl may actually be better-known than their service.

Along with potentially pumping up the userbase of a fledgling microblogging site, Twhirl has also position itself to be to these micropost what Trillian and Adium are to IM. Keeping several services readily accessible from the same app is a proven winner when it's done right, and Twhirl delivers on the usability and appearance side of things. It was already one of the most popular clients back when it could only handle Twitter, and its main competition is going to come from some of the better Twitter-specific clients that attract people who don't use the other sites Twhirl handles.

Seesmic, which is in private beta, is basically a micro-video-blogging service, which allows users to record and share short videos and respond to videos from other users. Seesmic has often been described as Twitter for video chat. Today that comparison becomes a bit more apt, as Seesmic has acquired Twhirl, one of the most popular desktop clients for Twitter.

Twhirl is one of several Twitter clients built on Adobe AIR which use Twitter's API to essentially make a web-page based service feel more like an instant messaging client. You can run Twhirl as a desktop application on your Windows, Mac, or Linux machine. When new messages come in, you get an alert, and you can sort messages by replies, directs, or personal and public timelines. Twhirl also recently added the ability to repost messages to other micrblogging services like Jaiku and Pownce.

So what does this acquisition mean? First and foremost, Twhirl will be getting Seesmic video capabilities soon. As you can see from the screenshot to the right, video messages will show up in a timeline just like Twitter messages. Users will be able to click on a video message to open up a window that will play the video.

Second, so far Twhirl's creator Marco Kaiser has been developing Twhirl in his free time. Yet he's been able to build one of the most capable Twitter clients around. Now that he's working for Seesmic, Kaiser will be able to work on Twhirl full time. We can hardly wait to see the results.

Not surprisingly, Seesmic founder Loic Le Meur decided to share his thoughts on the acquisition with a video. You can check it out after the jump.

Social video site Seesmic has announced some cool new features at DEMO08, a conference that showcases new software and web projects. Even though it's still in private beta, the so-called video Twitter now allows you to instantly see video responses to posts as an uninterrupted stream.

Now Seesmic also has a mobile application for Nokia's multi-talented N95 smartphone. Rather than being a live stream application such as like Qik, mobile Seesmic posts will be pre-recorded video snippets. You will also be able to view Seesmic videos on the mobile application.

While we're happy to see Seesmic branching out, we can't help but hope they touch more mobile phones than just the N95. Perhaps they can expand to additional Nokia handsets or even better yet, to Windows Mobile.
