I think anonymity is authenticity. It allows you to share in a completely unvarnished, unfiltered, raw way. I think that’s something that’s extremely valuable. In the case of content creation, it just allows you to play in ways that you may not have otherwise. We believe in content over creator.
There is an important true in this for sites of certain nature, but for Facebook which is essentially an online extension of offline life, it would not work without an online identity thats matched with a specified offline identity (or an on/offline synced identity).
