I like the other commenter's remarks about warrants. > are you more scared about data security in an online identity provider provided by the government or Facebook et. al.? Fair question. I'd still choose Facebook, mostly because they have an economic incentive not to screw it up. The government, on the other hand, has no such incentives. I mean, I trust both about as far as I can throw them, but at least one stays in business by practicing good security.
