So, not to make this a competition or anything... but who's winning? Is there a leaderboard for who has the most hats?
Sure there is. HATZ IS THE GREATEST COMPETITION EVER!!! if you don't know (so you don't need to make it a competition again).
Just go to http://winterbash2014.stackexchange.com/leaderboard to look at the current winners.
Everyone is winning!
While this event does tend to affect the overall inner workings by offering slightly weighted incentives which would otherwise be simply routine, it is still an awesome endeavor.
After all, it is the hat season, and all us cats are dressed up and ready to take the town :)
There is a leaderboard as noted by @nicael
Just got this today from an asian restaurant (I kid you not). I appear to have the universe on my side.
