title: What data can be obtained about a user who logs in with Facebook Oauth?
body: <p>I'm currently using OpenID to allow users to login to my website using Google as a provider.   I'm thinking about allowing users to use Facebook to login as well.  When a user logs in with Google OpenID, Google sends the following data to my website about the user:</p>
  
  <ul>
  <li>Full name</li>
  <li>First name</li>
  <li>Last name</li>
  <li>ID</li>
  <li>Gender</li>
  <li>Language</li>
  <li>Email address</li>
  </ul>
  
  <p>I've done some quick searching, but I can't find a list of attributes that Facebook would provide with an Oauth login.  What data does facebook provide by default, and what additional data can you ask for?</p>
