Twibes allows users to organize tweets by topic into interest groups called Twibes. Users can join up to 10 existing Twibes or create 3 of their own. To use Twibes, one searches for and joins a relevant Twibe by tweeting about its topic or keywords. Twibes collects tweets from its members on similar topics and adds them to the user's Twitter lists for easier viewing, but the tool has some functionality and search issues.
