The real question for me is, do people have the tools that they need in order to make those decisions well? And I think that it's actually really important that Facebook continually makes it easier and easier to make those decisions... If people feel like they don't have control over how they're sharing things, then we're failing them.

I personally don't invest in a lot of companies because I think it would be a conflict of interest and Facebook doesn't typically either.

Almost any mistake you can make in running a company, I've probably made

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

You know, you really don't need a forensics team to get to the bottom of this. If you guys were the inventors of Facebook, you'd have invented Facebook.

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.

This is a perverse thing, personally, but I would rather be in the cycle where people are underestimating us. It gives us latitude to go out and make big bets that excite and amaze people.
