Socialgrapes.com - Rank Profiles on Networking Sites (?)

According to Socialgrapes, there are 34,591,372 people on at least 11 different social networking sites. Yikes (how many are over 30?). Socialgrapes apparently wants to help you cull the wheat from the chaff by ranking people on those sites and coming up with the most popular or highest rated. I say "apparently" because the site has absolutely no description of what they do or what their mission is. So not only is the purpose of the site a mystery, but also I have no idea how this site works (unless I blindly missed everything). Aside from the "Mean Girls" type of social darwinism seemingly at work here, the site is sloppy, unorganized and unprofessional. It seems like they are just trying to capitalize on the social networking craze for a quick buck, but with little passion or purpose.

Wanna rate and track 34,591,372 people (Author"s note: that is the most I could find they had written about themselves).

I can not deny the revolution of the social networking sites.

Why have they not described the site, its mission, its founders, how to contact them, or its functionality? How are they planning on making a profit?
