Facebook is fast catching Yahoo and Google as US web users’ home on the web, having already overtaken MySpace and Microsoft in the past year. It has doubled in the past 6 months to nearly 30 billion total minutes usage, against Yahoo’s 40bn and Google’s just over 35bn.

And why? Mobile access is certainly a factor, but isn’t it just human psychology in that news is interesting, news about your friends even more so. Indeed perhaps it’s news about ‘strangers’ that is a big factor in MySpace’s fall from 17.5bn to 8bn in a year.
