> I'd venture a surprising number of people who really care about killing Facebook would back it, and a surprising number of people who don't care that much about Facebook would take the $50.

And an obscene amount would take the $50 and create a new account (or simply not reveal their real account).

I agree it'd be a fun experiment, though. And I see no reason to keep it hypothetical. I'd be particularly interested in seeing how much is raised (which I suspect would be relatively little).
