Although there's not a lot of space when it comes to retweeting, you can extract insights from what people are saying around them. That was what many of you said in commenting on my post the other day. That's where Retweetradar comes in.
Using the Google App Engine, Retweet Radar looks for trends in all of the re-tweeting over the last hour and pulls them into a nice tag cloud. It auto-refreshes every two minutes. Click on a term and it will take you to the conversation on search.twitter.com. (One of my hopes in 2009 is that Twitter finally integrates this into the main site.)
Nice effort by Ben Hedrington
