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.

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.

I’m here to build something for the long-term. Anything else is a distraction.

My number one piece of advice is: you should learn how to program.

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.

Some of the best ideas throughout the company's evolution have been from places all throughout the company whether it's an engineer or someone on the customer support team. Just different areas around the company.

In terms of doing work and in terms of learning and evolving as a person, you just grow more when you get more people's perspectives... I really try and live the mission of the company and... keep everything else in my life extremely simple.
