The thing that we are trying to do at Facebook is just help people connect and communicate more efficiently.

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

Virtual Reality is going to be an important technology. I am pretty confident about this.

The days of you having a different image for your work friends or co-workers and for the other people you know are probably coming to an end pretty quickly. Having two identities for yourself is an example of a lack of integrity.

For the first time we're allowing developers who don't work at Facebook to develop applications just as if they were. That's a big deal because it means that all developers have a new way of doing business if they choose to take advantage of it. There are whole companies that are forming whose only product is a Facebook Platform application.

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.

While we generally believe in free speech and giving everyone as much ability to speak as possible, in practice there are lots of barriers to that, whether it's legal restrictions, technological restrictions or you can't share what you want if you don't have access to the internet.
