I’ve been fortunate enough to test the TweetDeck User Streams Preview in a private beta over the last month, which enables TweetDeck to display a constant flow of Tweets, unencumbered by API rate limiting, in true real time. Last week User Streams entered public beta, and if you haven’t tried it, do it. Real-time Twitter is something Twitter veterans haven’t seen since May of 2008, and a vast majority of Twitter users have never really experienced it (unless they were among the few to turn on SMS updates for everybody). While this isn’t honest-to-God Twitter over XMPP (though the Streaming API will make such an application possible once more), this isn’t a bad alternative. Give it a try and let me know if you are overwhelmed — I know I was at first (I follow over 1700 people and bots on Twitter).
