This popped up in a few places yesterday – TweetDeck is slated to release a version of the Twitter client that shows updates in real time.

That doesn’t sound particularly impressive until you actually see it in action. Take a gander.

The functionality is soon to be available in a few other clients as well, according to various comments I’ve read about it today. Tweetdeck, so far, has the only demonstration up on the web of what it looks like.

If you want in on this, you’ll need to sign into the site with your Tweetdeck username and password and get on the “private beta whitelist.”
