Very nice. I have to ask, though, aren't you concerned at all about the NFL taking issue with this? They're pretty agressive at policing their trademarks. Using the term "Super Bowl" and images of the teams' helmets is probably a no-no, even if you're not making money off of this.

The domain in this context also violates Facebook's trademark and their rules about naming FB apps. Maybe also their ToS on promotions:
