I give up

I didn't find any major publications to rate or review on MySpace. Sure, Cosmo has a page but they aren't asking anyone to rate it. But I did find this little gem: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=857505
which was interesting, brief and has nothing to so with what I was searching for. The closest I came to relevance was this: http://blog.futurelab.net/2008/11/mediapost_publications_faceboo.html
Not so brief but basically states that businesses using social media are less connecting with people and more advertising to people. As I suspected!
