yea when you log into myspace, on the top header, it has forums, chat , search etc... do any of u post your sites on those forums?
A lot of people spam that forum, and all of them get ban, your allowed to post something helpfull, and you can have your website on the sig. But if your post is something stupid they will ban you. I use to post on that forum, but I would get maybe 1-2 visitors from there, not much.
I don't really see that happening any time soon. Didn't myspace just pass msn on Alexa to take 3rd rank? Google has some stake in Orkut, but its appeal is limited for now. I think they may have more important things to focus on (GoogleOS + gBrowser)
Yeah I wouldn't suggest using the MySpace forums for advertising, because they will ban you. I knew someone who tried that and was banned - he never even really got any visitors from it either..
