Our goal is not to build a platform; it's to be cross all of them.

We want Facebook to be one of the best places people can go to learn how to build stuff. If you want to build a company, nothing better than jumping in and trying to build one. But Facebook is also great for entrepreneurs/hackers. If people want to come for a few years and move on and build something great, that's something we're proud of.

With a generation of younger folks who have thrived on the success of their companies, there is a big opportunity for many of us to give back earlier in our lifetime and see the impact of our philanthropic efforts.

Building a mission and building a business go hand in hand.

When I was in college, I remember thinking to myself, this internet thing is awesome because you can look up anything you want, you can read news, you can download music, you can watch movies, you can find information on Google, you can get reference material on Wikipedia, except the thing that is most important to humans, which is other people, was not there.

I'm trying to make the world a more open place by helping people connect and share.

I think that people just have this core desire to express who they are. And I think that's always existed.
