Since there is literally nothing else going on in sports this afternoon, and because many of us will be watching it, how about a Super Bowl open thread?
No Puppy Bowl spoilers!
SBNation.com has comprehensive SB coverage, of course. Here's a stream on the commercials (with many of them already posted), and a stream on the game itself and everything associated with it. (If you 'like' that stream, all major updates will go straight to your Facebook news feed. It's quite useful for big events like this.)
