Yeah I gotta be honest the two sites I both like and hate most on the internet are Wikipedia and StackOverflow. Great resources in most cases but my god the moderation is.. overbearing.

I have my doubts that'll work for a social network. Good luck to them, but I'll have probably forgotten I signed up by the time they next send me an email.

Side note you seem to be able to bypass the signup queue by visiting your own friend share link.
