The battle for supremacy in the desktop Twitter client battle has been dominated by Tweetdeck and Seesmic and the latter has just upped the ante with the launch of its second version. Previously Seesmic, like Tweetdeck, rode on the back of Adobe Air but for the new service it has switched to Microsoft’s Silvernight.

Again, as with Tweetdeck, Seesmic takes social media up a level and enables you to manage a whole raft of social media platforms including, Foursquare, Google Buzz, LinkedIn and, naturally, Facebook. Integration with other services are enabled through plugins covering image facilities such as Yfrog and Twitpic, a translator, Twitlonger that enables you to go beyond 140 characters and others.

Enabling steams such as real time tweets, mentions, replies and DMs is simplicity itself and messages are colour coded to enable quick identification so mentions have a blue vertical line. I am not sure that this use of real estate is particularly beneficial; I would prefer to have narrower columns, but that’s just a personal thing.

Visually the new desktop is attractive but the lack of scheduling means I will be staying with Hootsuite.
