In just a few days before Chirp, Twitter just made a bold move to finally acquire a client and brand it as its own. Today both Atebits and Twitter formally announced the acquisition of Tweetie on their respective blogs. Some tension on its developer community (Seesmic, TweetDeck and etc) is to be expected, lets just hope Twitter founder Matt Evans can address this and clear things up in the upcoming conference.

Congrats both to Atebits and Twitter!
