Q:

Shall we participate in Winter Bash 2016? 

It's that time of year again: Winter Bash/hat
time!   Here's the
summary:

Winter Bash is an annual event that can run on any Stack
  Exchange site that chooses to participate.  Users have fun by
  earning "hats" for their gravatars by completing certain tasks
  (very similar to badges).  We track everyone’s progress using hats
  in a leaderboard

And here's some more detail:

The event will run from 19 December 2016 up to and including 08
  January 2017.   Users will be able to see all the hats they’ve
  earned on (http://winterbash2016.stackexchange.com).  That site
  will also have a landing page, explaining the rules and other
  details of the event. 
Individual users who don't want to participate, don't want to see
  hats, and/or are generally anti-hat will have an "I hate hats"
  option available.   And just like last time, at the end of the
  event, all hats will go back into storage. 
The only visual change to the Stack Exchange sites themselves will
  be the presence of the hats and the “I hate hats” button in the
  footer. 

Our default option at Emacs. SE is to participate in Winter Bash. 
Please take a moment to vote yes or no on our site-wide
participation (and/or comment on the options).   If there's a lot
of no votes, we can opt out collectively.
