The TweetBeat site provides real-time updates from and around the World Cup. You can follow what is being said about the whole tournament, or focus on a specific team and even follow what’s happening with its opposition. Not only that, but their Popular Tweets sidebar keeps you informed of what everyone else is talking about and, during matches, which team has the most Tweets.
TweetBeat uses the Twitter Firehose to cluster similar tweets into real-time stories from all across Twitter as they happen. You can use the speed slider to slow down or speed up the flow of Tweets and stories down the page. They have also integrated @Anywhere so that you can retweet the best tweets or follow your favorite Twitter users right from the site, without having to come back to twitter.com.
