Good stuff, Jeff.

More than a year ago, we made the same choice at BlueOregon.com.  BlueOregon is a site for progressive politics, particularly for and about Oregon.  And like most online sites, especially political ones, we were overwhelmed with trolls, spammers, and jerks - all using the shield of anonymity to throw their stinkbombs.

We decided to use Facebook, exclusively, as our authentication mechanism.  In our view, Facebook was (and is, with the possible exception of LinkedIn) the only authentication mechanism that is easy for users, widespread, and nearly guaranteed to be real identity.  (Twitter is great, but there's lots of anonymity on Twitter, and there's much less 1:1 correspondence between user accounts and actual humans.)
