Hmm, I have only a vague idea of what/who Vibrant is. I'm a long time reader, but I generally don't sign up for web sites (not even /.) I just finally signed up because you have to log in to sign up for a party.

Maybe that says something about my priorities. Won't sign up to anything for discounts, ease of use, saving preferences, or reduced advertising. But I'm all over signing up to party...

It might be interesting to see if there is a statistical difference between the percentage of AC posts before and after October 2007.
