For the past couple of weeks I've been involved in developing a new site called Tweetmeme and it launches today.
You can read all about it on the Tweetmeme blog, but in short it watches activity on Twitter and keeps track of popular URLs. There is a river of URLs, RSS feeds and it also posts new URLs that get promoted to the river in Twitter (@tweetmeme). The launch has been covered by Techcrunch.
I've had a lot of fun developing Tweetmeme and I hope it becomes a valued resource for the Twitter community.
If you're on Twitter feel free to follow me.
