I think a lot of the time there isn't such a black-and-white difference between what's a platform and what's an app. It's really just like the most important apps become platforms.

The basis of our partnership strategy and our partnership approach: We build the social technology. They provide the music.

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

I updated my grilling app, iGrill, today and it now has Facebook integration that lets you see what other people are grilling right now around the world. Awesome.

I like making things. I don't like getting my picture taken.

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

We're running the company to serve more people.

The amount of trust and bandwidth that you build up working with someone for five, seven, 10 years? It's just awesome. I care about openness and connectedness in a global sense.

When Facebook was getting started, nothing used real identity - everything was anonymous or pseudonymous - and I thought that real identity should play a bigger part than it did.

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

I started the site when I was 19. I didn't know much about business back then.

About half my time is spent on business operation type stuff.

It's really easy to have a nice philosophy about openness, but moving the world in that direction is a different thing. It requires both understanding where you want to go and being pragmatic about getting there.

I think humans are just hard-wired to process people's faces and understand meaning and expression at such a more granular level than other types of communication.

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.

The real story of Facebook is just that we've worked so hard for all this time. I mean, the real story is actually probably pretty boring, right? I mean, we just sat at our computers for six years and coded.

I literally coded Facebook in my dorm room and launched it from my dorm room. I rented a server for $85 a month, and I funded it by putting an ad on the side, and we've funded ever since by putting ads on the side.

If you grew up, and you never had a computer, and you've never used the Internet, and someone asked you if you wanted to buy a data plan, your response would be 'What's a data plan, and why would I want to use this?'

We help Chinese companies grow their customers abroad. They use Facebook ads to find more customers. For example, Lenovo used Facebook ads to sell its new phone. In China, I also see economic growth. We admire it.

The thing that's been really surprising about the evolution of Facebook is - I think then, and I think now - that if we didn't do this, someone else would have done it.
