Among Twitter desktop apps, Seesmic and TweetDeck are the two biggest, built using Adobe AIR, which allows them to work on multiple operating systems. However, AIR has limitations, since it essentially helps port rich Internet applications onto the desktop. Adding plug-ins and drag-and-drop functionality are just two examples.
That functionality is about to come to Seesmic though, and its moves today could change the dynamics of the Twitter app race. The company has just announced the launch of Seesmic for Windows on the stage of the Microsoft Professional Developers Conference. This is no Adobe AIR App: this is a fully-functional desktop program that utilizes some of the best features of Windows 7. It is available by request at Seesmic.com
Seesmic for Windows, whose preview will be available today, is a project that has been in the works for months. The goal was to allow outside developers to more easily integrate their products with Seesmic. The Windows version does that through a plug-in system that’s similar to what you’d find in Firefox. Tweetmeme and MrTweet, for example, should be available as plug-ins by the final launch.
Seesmic for Windows also boasts some new features and improvements from its AIR counterpart. Specifically, you can drag-and-drop users into lists and other parts of the app, it uses less memory, and it utilizes several Windows 7 features (e.g. location sensor).
Seesmic seems intent on becoming the Twitter app of choice for third party developers. It makes sense: the strategy worked very well for Twitter itself. Still, it does divide the company’s attention, especially as its competitor TweetDeck has a popular iPhone app out on the market. There is also no indication if or when a Mac version will be released.
We’re going to play with Seesmic for Windows and give you our assessment. In the meantime, let us know what you think in the comments.
