I think that ranking high on the leaderboard, as a community, is good publicity for Code Review. I'd like us to rank high, and all members to get a lot of hats, but without abusing the rules, staying legit. Some hats are easy to get, while some are harder, or even very hard. (If it was easy, then what's the point anyway?)
How can we get the most out of Winter Bash 2015, without crossing some sort of lines?
