I understand that FB Connect is a turn off for many people (myself included most of the time). But requiring Facebook makes certain viral features (like sharing with your friends, posting to your wall etc) much more frictionless. I think there are 3 ways a site can become popular. 1) Through viral channels. 2) Through word-of-mouth. 3) Through marketing/pr. I'm going for all three. #1 is a lot easier if you require FB Connect.
