Hey HNers, I created a game / prediction net where people can tweet in final score predictions for the upcoming March Madness NCAA games. To play you have to post a tweet that includes "@scorecaster" or "#scorecaster", the hashtag for the game (they are listed on the site), and the score prediction (in the same order as the teams in the hashtag), example: "@scorecaster #UMvMU 65-55".

I wanted to make something that adds a playful, social element to watching sports. I tweet and chat with friends back home when watching basketball games, and I wanted to have a way to sort of trash talk/compete with one another. Something more casual and less formal than betting, and more social.

I'd love to get feedback from all of you. My biggest concern is that it might not actually be very fun to try to predict the final score of a game. Sometimes it feels quite arbitrary to me. I'm looking for ways to make that more interesting. If I get a critical mass the first thing I'd want to add is the ability to restrict the leaderboard and predictions list to people that are connected to you on twitter.
