The big tech news today is that TweetDeck has been purchased by Twitter . I'm fine with it. Sure, I'm a little concerned that Twitter may ruin TweetDeck by, say, dropping support for Facebook and other social networks. But, hey, it's a Twitter app. I can and do use HootSuite (as well as TweetDeck ), so unless Twitter goes on some massive buying spree to eliminate all competition, I still have alternatives if Twitter decides to get stupid with TweetDeck. Besides, TweetDeck is doing some really innovative things these days, and Twitter proper could use some innovation. So I remain hopeful.
