I've seen 12 talks and one tutorial and a half, including speakers such as Tim O'Reilly, Larry Wall, Damian Conway, Alan Cox, Abigail and Autrijus Tang. These talks involved very interesting subjects, from CPANPLUS to pugs^WPerl6.
I've played Werewolf the last two nights, and I actually managed to win one of games when I was a Werewolf myself (and also some of them when I was a vilager, I believe).
I've met a lot of wonderful people around here. I've also seen a lot of familiar faces.
I really love conferences
