I sort of wish MySpace stayed a going concern though.
It provided the social-network Internet a much-needed "wrong side of the tracks". As it dwindles, that's all coming to Facebook now.
Although I suppose proper management of your friends network should mean you don't see anyone/anything you don't want to.
I think facebook has the trick of keeping that from happening. The have very few means of browsing liss of users, and it requiers more effort and specfic details to find people. On myspace, I would get request from people trolling for dates and such. That does not happen on facebook.
Myspace died because it combined elements of dating sites, social networking and personal webpages.
Facebook does not, which keeps it viable and keeps the dumdums in check.
