Looks like google's integration / partnership with Twitter and friends has put something pretty interesting out there. Check out the video of Relevance meets the real-time web over on the Google blog. Basically results will have "real time" results brought in with AJAX magic from Twitter, Identica, Facebook, etc in a cool scrolling box. The features aren't rolled out yet, but you can check it out on the Trends page under hot topics. IE: check out this search for joojoo.
