I will fully admit to not having watched a single second of AI; I can't handle the show itself, largely because the judges drive me crazy. But they do tons of joint interviews, etc. and you can get just about all the good bits on youtube. It's totally possible to be in AI fandom without watching AI; tons of people do it! :)

Also, I think WC is the first fandom I've found where the primary pairing seems to be a threesome; Peter/Neal/Elizabeth is happy OT3 land! :D
