If you want to be free, or you want to preserve freedom for people, you both need to have laws that make it so people have freedom of speech and all the freedoms that they need. You also need to have an open governance system where people can vote and people have representation.

Stuff like photos and events and groups - we've built pretty basic versions of those apps to start but they ended up being so much more used because of their social integrations.

The primary things that people do on the Facebook is they use it to share with their friends and the people around them and their community, and they use it to keep in touch with people.

People at Facebook are fairly used to the press being nice to us or not nice to us.

The companies that work are the ones that people really care about and have a vision for the world so do something you like.

No one has done a study on this, as far as I can tell, but I think Facebook might be the first place where a large number of people have come out. We didn't create that - society was generally ready for that. I think this is just part of the general trend that we talked about, about society being more open, and I think that's good.

My friends are people who like building cool stuff. We always have this joke about people who want to just start companies without making something valuable. There's a lot of that in Silicon Valley.
