There are far too many stats to include them all in the closing blog post, so I figured I'd tie the rest in the bow and post them.

Just Here for the Hat...Stats
This hat was similar to last year's, 'Every! Body! Gets! A Hat!', where users earned the hat when they collectively earned 20 distinct hats. We had a total of 160 sites participate in Winter Bash, and 108 communities earned Just Here For the Hat. Here is the breakdown of sites who earned the hat, and how many users it took to get it (actually, the number of users is an approximation).

Stack Overflow vs. The Rest of the Network
This was the first year that Stack Overflow users were automatically opted into hats, which is partly why there was such an increase in the number of hats awarded. Last year, 322,747 hats were given out to 72,182 users, but this year 797,074 hats were awarded to 215,960 users.
Out of curiosity, I took a closer look at the Stack Overflow numbers versus the rest of the network to see if there were any hats that were awarded significantly different.

The top 8 hats awarded on Stack Overflow matched the overall network stats, but then 24, the gold badge hat, comes in as the most popular behind most of the date-based hats. Some takeaways:
- Even though it was not a secret hat, fewer Stack Overflow users got the Cutting the Cord hat (904) versus the rest of the network (1,132).
- The non-secret hat, Search You Must, was awarded significantly more on Stack Overflow (6,386) when compared to the rest of the network (1,908).
Miscellaneous Things
- December 21st was the most active date for hats being awarded. There were 81,472 hats awarded to 39,778 unique users. Just Here for the Hat made up 37,213 of those hats, followed by both Where in the World? hats - the Sun version was awarded 16,411, and the Moon version 15,069 times.
- The least active date for hats being awarded was the last day of hats, January 8th. Only 6,945 hats were awarded to 4,247 users.
- The very first hat awarded was I Am Your Father on December 19th at 0:09.
- 925 was the last hat awarded in Winter Bash, and it was awarded on Mathematics Educators.
- Alexander O'Mara was the first to get 6 hats during Winter Bash, including Third Time's A Charm, 011. He was followed closely by Samuel Liew who was the first to earn 5 hats, including Cutting the Cord and Hero of Questions.
There were a total of 8 users who earned all possible secret hats on a single site:
Final Thoughts About Winter Bash 2016
While we may have had a few issues aka bugs that unexpectedly popped up during Hat Season, I personally think it was a rousing success. Since hats were seen by all users on Stack Overflow, including anonymous users, initially we were concerned about performance impacts, but there were none.
As in previous years, I think the biggest that comes up during hat season is soul-selling for hats. We try extremely hard to create hats that encourage positive behavior and are for things users already do during their daily participation. Unfortunately, there are always cases where hats get the best of folks, and they go a bit crazy trying to earn them. I'm not sure what the solution is. Maybe no secrets hats? If all the triggers are known, then possibly it would minimize the amount of science to get a hat.
We also tried to space out when hats, specifically date based ones, were awarded. Winter Bash is typically about three weeks long, so if you earn all the hats in 1-2 days, it's a long 3 weeks of not having fun trying to earn new hats. Patience is virtue in many things, it's no different in hat season.
There are plenty of other stats that could be pulled about hats. If I think of something interesting, I'll post an update. Remember, if you have suggestions for next, chime in on this question. Thanks again for participating and having fun with us again this year. But for now...
