I hope you all take this as interesting and not spam. I've been working on a project to link Red Sox fans at the game with fans watching it everywhere else (home, bar).
We are launching mobile apps for iPhone, android and Blackberry to make this possible. I'm working on this, because I think it would be awesome to have a way to interact with fans actually at the game while I'm sitting on my couch watching.
If this sounds interesting, you can take a look at what we're working on at phanoto dot com.
Again, hope this doesn't come off as spammy - I know my boss is planning on getting in touch with the owners of this site to work something out.
