Openness fundamentally affects a lot of the core institutions in society - the media, the economy, how people relate to the government and just their leadership.

The web is at a really important turning point right now. Up until recently, the default on the web has been that most things aren’t social and most things don’t use your real identity. We’re building toward a web where the default is social.

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.

We want Facebook to be one of the best places people can go to learn how to build stuff.

Google, I think, in some ways, is more competitive and certainly is trying to build their own little version of Facebook.

Our strategy is very horizontal. We're trying to build a social layer for everything. Basically we're trying to make it so that every app everywhere can be social whether it's on the web, or mobile, or other devices.

If you're always under the pressure of real identity, I think that is somewhat of a burden.
