No and no. Neither MySpace nor Friendster ever had anything near a half billion users. Facebook has gotten to the point where the government would step in if they wanted to destroy all of the photos.

Mostly, I think Facebook has achieved the status of a utility. It is entrenched, with a solid business model. It's drastically different than Myspace and Friendster in that way. They were just fads.

Also, GeoCities was at least partially saved. As we develop more computing infrastructure of all kinds, that kind of thing becomes more an more likely.
