UPDATE We're in for the hats this year. We just submitted the form!
Last year, Stack Exchange ran Winter Bash 2013, in which users earned hats which they proudly displayed upon their gravatar. There was a leaderboard of hatters, mad or not:
It's that time of the year again and we get to choose whether we want to do it again this year. Hats are enabled on a per-site basis, but each site has to opt-in and choose to participate.
What are hats, I hear you ask. Well, hats are kinda like ephemeral badges. You can choose to have one displayed over your avatar and you win them by certain actions on the webpage. Users can turn off hats on a per-user basis, so if you're against them for any reason, you can disable the feature and not see your hats nor those of the users who have opted in. As far as you are concerned, the hats will not exist.
If we choose to accept, the event will run from 15 December 2014 to 4 January 2015. After that, all the hats go away into Last Year's Hat Bin.
We need to decide if we want hats by December 1. So, do we like hats or hate hats?
