I was not much impressed with MySpace.
I have done nothing with it since I joined May 2006.
But Facebook seems to be a quantum leap superior site for social networking.
Security is good. And Facebook is the number one site for hosting photos with 2.3 million pics uploaded daily. (I will keep mine on Flickr, for now.)
I already have 6 “friends”.
