it seems that google has given all profile pages of
www.myspace.com a pr5 and each profile is aloud to add in outbound links
i.e if u can get a couple of people to link your site from their profile u have inbound pr5's to your site which should increase your own pr and therefore the relevance of your search engine keywords and how well they rank in the engines
Pr in google especially is important .. the higher your pr the higher your listings
if i have a keyword for oprano in one of my pages and its pr5 and u have the exact same keyword and yours is pr4 i will get listed higher
anyways .. point being get some links from myspace profiles and increase ur own eventual pr
