It's often not said enough, but the goal of Facebook during its history has always been to connect <i>real</i> people -- places like Twitter offer the opportunity to create humorous pseudonyms and fake identities, but Facebook (and Google+ for that matter) are about connecting people and fleshing out those connections.

A point that's overlooked: MySpace allowed pseudonyms to run free and wild, but that's what made the connections on the site all-the-more shallow.
