Last year, Stack Exchange threw an end of the year party featuring special hats, and they're doing it again this year. But because hats might not be appropriate for all Stack Exchange sites, they're asking each community whether or not they want to participate.
Last time, we decided that we liked hats. So I guess the question is: do we still like hats?
What are hats, you ask? Well, they're kind of like badges. You earn them by doing various things. But unlike badges, they look like hats, and once you've earned a hat you can choose to wear it on your avatar! And they're purely temporary, just for fun. They'll disappear once Winter Bash is complete.
Note: users who don't want to see hats will be able to click a button labeled "I hate hats".
