We have a rule that if you check in code, you have to maintain it. So I mostly code on the side. I don’t check in code anymore.

A lot of times, I run a thought experiment: ‘If I were not at Facebook, what would I be doing to make the world more open?’

On engagement, we’re already seeing that mobile users are more likely to be daily active users than desktop users. They’re more likely to use Facebook six or seven days of the week.

People at Facebook are fairly used to the press being nice to us or not nice to us.

If we’re trying to build a world-class News Feed and a world-class messaging product and a world-class search product and a world-class ad system, and invent virtual reality and build drones, I can’t write every line of code. I can’t write any lines of code.

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.

After launching the first version of Facebook for a few thousand users, we would discuss how this should be built for the world. It wasn’t even a thought that maybe it could be us. We always thought it would be someone else doing it.

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.

All of my friends who have younger siblings who are going to college or high school – my number one piece of advice is: You should learn how to program.

Facebook is in a very different place than Apple, Google, Amazon, Samsung, and Microsoft. We are trying to build a community.

Our goal is to make it so there’s as little friction as possible to having a social experience.

We talk about this concept of openness and transparency as the high-level ideal that we’re moving towards at Facebook. The way that we get there is by empowering people to share and connect. The combination of those two things leads the world to become more open.

There is a huge need and a huge opportunity to get everyone in the world connected, to give everyone a voice and to help transform society for the future. The scale of the technology and infrastructure that must be built is unprecedented, and we believe this is the most important problem we can focus on.

I got my first computer in the 6th grade or so. As soon as I got it, I was interested in finding out how it worked and how the programs worked and then figuring out how to write programs at just deeper and deeper levels within the system.

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 started off as this platform inside Facebook; and we were pretty clear from the beginning that that wasn’t where it was going to end up. A lot of people saw it and asked, ‘Why is Facebook trying to get all these applications inside Facebook when the web is clearly the platform?’ And we actually agreed with that.

When we were a smaller company, Facebook login was widely adopted, and the growth rate for it has been quite quick. But in order to get to the next level and become more ubiquitous, it needs to be trusted even more.

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

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. So inherently, our whole approach has to be a breadth-first approach rather than a depth-first one.

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