Re: Jeez
The problem is that people expect to be able to login using their FB profile and then the service know their name, possibly DoB and other details.
That's part of the whole SSO mentality - it's their 'profile' across all of the services they use, not just an authentication thing.
It's also the reason that I go to the effort of creating an account on each service and not using some third-party authenticator,
