Echofon and Tweetdeck announced that it has 5,000 invites for testing the next generation version of Tweetdeck with Twitter's new User Stream API enabled. The API brings "Real-Time Web" with instant delivery of information; no more refreshing required. When someone replies, retweets or favorites a tweet, you'll see it all happen in your stream milliseconds after the person has done it.
"Tweetdeck says that "User Stream API is "real" real-time that'll make tweets, follows, replies, friend discovery – basically everything on Twitter – faster. "We've been working closely with Twitter to develop a version of TweetDeck that makes use of their User Streams API," and that only really large third-party apps such as Tweetdeck are getting a chance to play with User Stream API at this time.
