Make hats encourage good/desired behaviour.
- Hairboat's Revenge, for instance, is just silly: it caused a lot of unnecessary comments and clutter. Suggestion for next year: abolish it. If the CMs want to play Christmas pranks on each other, can't they do it without causing a lot of mess for everyone?
- Timey Wimey might have seemed like a good idea, but in practice it encouraged people to do lots of insignificant edits and clutter up the front page with old questions just to get a hat. Suggestion for next year: require edits to be substantial (by some definition).
- Greeter also probably seemed like a good idea, but it caused some problems on sites with a high volume of low-quality posts.
(Admittedly Winter Bash 2015 was much better on this front than Winter Bash 2014. Kudos to Pops and whoever else was involved!)
