Winterbash 2014 is coming!* 'Tis the season of earning silly hats for your avatar to wear by achieving achievements in Stack usage. Not only are these achievements more "fun", off-kilter, and promote a sense of community festivity than the usual goals for getting badges, but they earn you hats. Some are secret criteria for secret hats, but the non-secret hat criteria are listed on the Winterbash 2014 site, for which you earn hats.
Did I mention there are hats.
So get your heads (or dice, abstract concepts, other hats, pets, or whatever your avatar displays) ready, because Winterbash starts December 15th (site time) and runs until January 5th. For those who are new to RPG.SE since the last Winterbash, the Winterbash 2013 site and FAQ should give you an idea of what to expect.
And should you have an unreasonable, irrational, ridiculous but totally respected hatred of hats, you can opt out and have a 100% hat-free holiday site experience.
Site not yet live! But it is already alive in our hearts.
