Myspace. Friends with 1000000001 requests to join their game, tons of spam, “here install this (virus) to see who is looking at your facebook account”. It’s all there . Everything that was on myspace is on facebook. But so many people got sold to the advertisements, they actually believed it was their opinion. And then News Cop (owners of Myspace) made a bonehead move and totally and completely bloated the website with some stupid top and bottom menu. Now there is no reason to stay there, you can not navigate that site.
So all we have now is the least Social Network, facbook.
