We are a mission-driven company. In order to do this, we have to build a great team. And in order to do that, you need people to know they can make a bunch of money. So we need a business model to make a lot of money.

The connectivity declaration is about uniting the whole industry - a lot of companies that typically compete very fiercely - to push in a coherent direction.

It wasn't until we got our first office in Palo Alto where things became more like a company. We never went into this wanting to build a company.

We have a very open culture at the company, where we foster a lot of interaction between not just me and people but between everyone else. It's an open floor plan. People have these desks where no one really has an office. I mean, I have a room where I meet with people. But it has all glass, so everyone can see into it and see what's going on.

The biggest mistake we made as a company was betting too much on HTML5.

Founding a company is hard. Most of it isn't smooth. You'll have to make very hard decisions. You have to fire a few people. Therefore, if you don't believe in your mission, giving up is easy. The majority of founders give up. But the best founders don't give up.

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.

We're running the company to serve more people.

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.

When we are thinking about stuff like embeds, we are not thinking about how we are competing with YouTube. We are thinking about how are we going to make it more useful for people to share stuff on Facebook.

Look at the way celebrities and politicians are using Facebook already. When Ashton Kutcher posts a video, he gets hundreds of pieces of feedback. Maybe he doesn't have time to read them all or respond to them all, but he's getting good feedback and getting a good sense of how people are thinking about that and maybe can respond to some of it.

I remember flying in, driving down 101 in a cab, and passing by all these tech companies like Yahoo! I remember thinking, 'Maybe someday we'll build a company. This probably isn't it, but one day we will.'
