Nice way to organize tweets. If you want to stay on top of an issue then Revisit is your best ally. The website is a real-time visualization of the latest tweets on any topic. Newer and more important tweets show up and are highlighted. You see tweets from the last ten days and it is suggested you keep them under 200. Twitter users can use the site to create their own twitter wall, say, at a conference or other type of event where that is appropriate. Color connections indicate the tweet's connections to others (via retweets or @replies). There is no signing up and instructions are straight forward.
