Twitter has acquired desktop client TweetDeck, the companies have confirmed.
"I am extremely happy and proud to let you know that TweetDeck has been acquired by Twitter," TweetDeck founder Iain Dodsworth announced on his company's blog today. "We completed the deal on Tuesday and are now in the process of 'joining the flock.'"
Twitter's acquisition of TweetDeck, a favorite among Twitter users, isn't all that surprising. Since last month, reports have been swirling that the companies were in negotiations. And earlier this week,that the social network had agreed to acquire TweetDeck, which provides a "personal browser" for staying in touch with updates from users on Twitter, as well as Facebook, MySpace, and LinkedIn, for $40 million in cash and stock.

And Dodsworth expects TweetDeck to continue to support multiple social network platforms. "The reality of it is that TweetDeck usage has been heavily Twitter-based with the external services not heavily used but acting more as a value-add for our users. I can't see them going away anytime soon," he told All Things Digital.
