At this point facebook is just a branch of the NSA and CIA. They're laughing it up while the clueless kid Zuckerberg thinks he's creating "a social graph". How about an "open" social graph you jackass - you know, THE WEB.
Hopefully governments step in to break up this evil oonopoly that's on it's way to another microsoft, AT&T, Standard Oil. However, it might too late already, since the NSA and CIA desperately want facebook to exist.
