I'd like to show an improved product rather than just talk about things we might do.

It's tough to say, exactly, what things will look like in three to five years, but there's a lot of work to do in just moving along the path that we've already set out.

Facebook was not originally created to be a company. It was built to accomplish a social mission - to make the world more open and connected.

Facebook is really about communicating and telling stories... We think that people can really help spread awareness of organ donation and that they want to participate in this to their friends. And that can be a big part of helping solve the crisis that's out there.

In a world that's changing so quickly, you're guaranteed to fail if you don't take any risks.

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.

The question isn't, 'What do we want to know about people?', It's, 'What do people want to tell about themselves?'
