But I really believe that when you give people authentic identity, which is what Facebook does, and you can be your real self and connect with real people online, things will change.

I don't believe we have a professional self from Mondays through Fridays and a real self for the rest of the time.

I don't believe we have a professional self Monday through Friday and a real self the rest of the time. It is all professional, and it is all personal.

Pages on Facebook are allowed to be anonymous. That is really important. People start revolutions; we need anonymity.

We and others have done a bunch of work to show that if your real friends online say or do something, it affects you. But if your acquaintances online say or do something, it does not. People on average have about 106 Facebook friends, but only 5 or 6 real friends.

When you're with real people, you don't have to be with virtual people.
