I have been using SportsTwit to track games that I can't watch. It has been around for quite a while: <a href="http://www.sportstwit.com/" rel="nofollow">http://www.sportstwit.com/</a>
This is a great application of the live microblogging concept. People simply love to get live updates about sports specially when you at work. Every live game spectator has a mobile phone, I can imagine them sending thousands of updates per game.<p>I do not care for sports, but this is one great idea.
