I think there's confusion around what the point of social networks is. A lot of different companies characterized as social networks have different goals - some serve the function of business networking, some are media portals. What we're trying to do is just make it really efficient for people to communicate, get information and share information.

I think Facebook is an online directory for colleges... If I want to get information about you, I just go to Facebook, type in your name, and it hopefully pulls up all the information I'd care to know about you.

I think that more flow of information, the ability to stay connected to more people makes people more effective as people. And I mean, that's true socially. It makes you have more fun, right. It feels better to be more connected to all these people. You have a richer life.

There have been misperceptions that we're trying to make all the information open on Facebook, and that's completely false. There are big buckets of information that we recommend that you share with only your friends privately. Then some of the more basic information, we recommend that that's visible to everyone.

Money was never a big motivation for me, except as a way to keep score. The real excitement is playing the game.

Money is not the motivating force. It's nice to have money, but I don't live high. What I enjoy is running the business.
