When you give everyone a voice and give people power, the system usually ends up in a really good place. So, what we view our role as, is giving people that power.

People think innovation is just having a good idea but a lot of it is just moving quickly and trying a lot of things.

We used to write this down by saying, 'move fast and break things.' And the idea was, unless you are breaking some stuff you are not moving fast enough. I think there's probably something in that for other entrepreneurs to learn which is that making mistakes is okay. At the end of the day, the goal of building something is to build something, not to not make mistakes.

If you don't risk anything you risk everything

I made so many mistakes in running the company so far, basically any mistake you can think of I probably made. I think, if anything, the Facebook story is a great example of how if you're building a product that people love you can make a lot of mistakes

Stuff like photos and events and groups - we've built pretty basic versions of those apps to start but they ended up being so much more used because of their social integrations.

The thing I really care about is the mission, making the world open.
