Twitter in real time. Mind. Blown. [Videos] - The Next Web

... the availability of preview beta releases of their respective twitter clients featuring twitters new user stream API. The API essentially brings real time to twitter; no more refreshing required. When someone replies, retweets or favorites a tweet, youll see it all happen in your stream milliseconds after the person has done it.

It really has to be seen to be believed. If you were an avid Friendfeed user, this should bring back memories.

... agree&. I mark as favorite the last message I read and then refresh and I know which twit was the last one I read& with this stream I cant make up from down.

This is why it needs to be animated smoothly, none of this instant appearance rubbish. I eyes can detect motion you know! MOTION!

Interesting. I agree lists will be important with a feature like this however there is a downside to lists&.they dont show the new retweets. They still work for old RT style retweets. That is a HUGE limitation and makes lists unusable for monitoring your twitter stream.
