There should be a way to compare players on a same screen in select categories or stats. That would be pretty sweet.

i think it's a good idea. some of us are just stat junkies and like to look at numbers. additionally, i'd like to see a way to 'track/follow' other players who I've maybe noticed on the leaderboards has similar 'trends' as mine, but without friending them. sort of like a 'stalking' feature but without the weirdness or fear of a restraining order. j/k

Agreed. The stats page could use a feature like the one you described.
