It also gets you the worst of both worlds, in that you have to build both a Facebook auth solution, and store some form of user password hash on your servers

  And the worst of all worlds for the user. When I use Facebook logins for a site, it's because I don't know if there's value in the site so I want signup and evaluation to be as quick and painless as possible. I don't want to have to go through other steps, I want a one-click registration and login. A pet peeve of mine is when I click on the login with facebook button and the site still makes me fill out my name, username, email address, and set a password. So what's the point of logging in with facebook?

    It's so a) they get all you and your friends' social data, b) they can prefill your signup form and 3) to make sharing easier and friction-free.

    I'm assuming that you have multiple (throw-away)-facebook accounts? Because you don't give a site that you don't know has any value access to your facebook account? Right?

      I have one throw away with no friends and no info (I consider this best-practice) for these situations.
