Pundit Tracker Website
 

I stumbled across this via a Deadspin link. They track the accuracy of media figures (pundits) with regards to games predictions. Looked interesting:

Oh, to clear it up a bit, they go by a system that's similar to betting. Kind of like what would happen if you bet one dollar on theses guys' predictions. They publish individual "yields", or what you would win off of that dollar.
