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.

When I see a story, I ask: is this something I’d like to be in? Is this something I’d like to see? And if I’d like to see it, would I like to tell it?

I see fighters make funny videos about me and stick them on Facebook and get 20 likes. When I make a video, I sell it to Fox and make seven figures. That’s the difference.

People are generally amazed that I would take an interest in any forum that would require me to stop talking for three hours.

One of my big regrets is that Facebook hasn’t had a major chance to shape the mobile operating system ecosystem.

Everybody is a political person, whether you say something or you are silent. A political attitude is not whether you go to parliament; it’s how you deal with your life, with your surroundings.

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?‘

I actually don’t read most of the coverage about Facebook. I try to learn from getting input from people who use our services directly more than from pundits.

This is our commitment to users and the people who use our service, is that Facebook’s a free service. It’s free now. It will always be free. We make money through having advertisements and things like that.

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.

We’re a community of a billion-plus people, and the best-selling phones – apart from the iPhone – can sell 10, 20 million. If we did build a phone, we’d only reach 1 or 2 percent of our users. That doesn’t do anything awesome for us. We wanted to turn as many phones as possible into ‚Facebook phones.‘ That’s what Facebook Home is.

Thinking is the hardest work there is, which is probably the reason why so few engage in it.

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.

A business has to be involving, it has to be fun, and it has to exercise your creative instincts.

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.

A good essay must have this permanent quality about it; it must draw its curtain round us, but it must be a curtain that shuts us in not out.

I mean, we’ve built a lot of products that we think are good, and will help people share photos and share videos and write messages to each other. But it’s really all about how people are spreading Facebook around the world in all these different countries. And that’s what’s so amazing about the scale that it’s at today.

Refuse to be a lazy Christian, and resist a passive, apathetic attitude.

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.

Think about what people are doing on Facebook today. They’re keeping up with their friends and family, but they’re also building an image and identity for themselves, which in a sense is their brand. They’re connecting with the audience that they want to connect to. It’s almost a disadvantage if you’re not on it now.

Facebook is quite entrenched and has a network effect. It’s hard to break into a network once it’s formed.

Facebook is inherently viral. There are lots of sites that include a contact importer, and for lots of them it doesn’t really make sense. For Facebook it fits so well. It wasn’t until a few years in that we started building some tools that made it easier to import friends to the site. That was a huge thing that spiked growth.

Facebook and Instagram are both really popular with teens, both in the U.S. and globally across the world. I think what you’re starting to see is that there are all these different ways that people want to share and communicate.

I hope that Facebook and other Internet technologies were able to help people, just like we hope that we help them communicate and organize and do whatever they want to every single day, but I don’t pretend that if Facebook didn’t exist, that this wouldn’t even be possible. Of course, it would have.

I just think people have a lot of fiction. But, you know, I mean, 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 mean Facebook is no longer a company, it’s a country. 2 billion users. It can influence what we think, what we believe, how we vote, what we buy, even how we feel.

In the spring of 1936, I was introduced by friends to Jean Tatlock. In the autumn, I began to court her. We were at least twice close enough to marriage to think of ourselves as engaged.

Social media is called social media for a reason. It lends itself to sharing rather than horn-tooting.

Video is growing very quickly on Facebook. A lot of people compare that to YouTube. I think that kind of makes sense. YouTube isn’t the only video service, but I think it’s the biggest, and it probably makes more sense to compare Facebook video to YouTube rather than Netflix because that’s a completely different kind of content.

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.

This younger generation that’s around, that’s tweeting, Facebooking and Vine-ing, the fans appreciate that because they feel like they can get to you.

For in the end, freedom is a personal and lonely battle; and one faces down fears of today so that those of tomorrow might be engaged.

My readers – and I get 400 emails for a day, my readers normally they say, well, you understand me, and I answer, you do understand me also. We are in the same level.

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.

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

When I started Facebook from my dorm room in 2004, the idea that my roommates and I talked about all the time was a world that was more open.

The main Facebook usage is so big. About 20 percent of the time people spend on their phone is on Facebook.

I love going one-on-one with someone. That’s what I do. I’ve never lost. It’s a whole different game, just to have them right in front of you and be able to do whatever you want.

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’m very active on social media and see the huge impact it has on engaging with fans and being able to have a voice.

Twitter is my bar. I sit at the counter and listen to the conversations, starting others, feeling the atmosphere.

The two most engaging powers of an author are to make new things familiar, familiar things new.

Working with a lot of people at the same time is a task. I really like making stuff and getting stuff done. One of the things I really liked about Facebook was that I could always move so quickly. I wrote the original application in, like, nine days at the end of January.

It’s not that every single thing that happens on Facebook is gonna be good. This is humanity. People use tools for good and bad, but I think that we have a clear responsibility to make sure that the good is amplified and to do everything we can to mitigate the bad.

If somebody crafts an interesting tweet that’ll lead me to their blog, I’m going to their blog.

At Facebook, we build tools to help people connect with the people they want and share what they want, and by doing this we are extending people’s capacity to build and maintain relationships.

Health is certainly extremely important, and we’ve done a number of things at Facebook to help improve global health and work in that area, and I am excited to do more there, too. But the reality is that it’s not an either-or. People need to be healthy and be able to have the Internet as a backbone to connect them to the whole economy.

In the normal flow of a conversation, our attention is divided. We hear parts of what other people are saying, in order to follow and keep the conversation going. At the same time, we’re planning what we’ll say next, some exciting story of our own.

Once people are aware of your presence, and perhaps vaguely intrigued, you need to stir their interest before it settles on someone else.

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.

I can move any crowd.

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.

Facebook is really about communicating and telling stories… We think that people can really help spread awareness of organ donation and that they want to participate in this to their friends. And that can be a big part of helping solve the crisis that’s out there.

What I have never been afraid of is to be a little silly, and you can engage people that way. My view is, first you get them to laugh, then you get them to listen.

There are a few other things that I built when I was at Harvard that were kind of smaller versions of Facebook. One such program was this program called Match. People could enter the different courses that they were taking, and see what other courses would be correlated with the courses they are taking.

If it’s all instruction, you get annoyed with it and bored, and you stop reading. If it’s all entertainment, you read it quite quickly, your heart going pitty-pat, pitty-pat. But when you finish, that’s it. You’re not going to think about it much afterward, apart from the odd nightmare. You’re not going to read that book again.

You might be the funniest guy in the world, but if you don’t have anything to talk about, people are eventually going to gravitate towards the guy that’s actually saying something.

I think Facebook is an online directory for colleges… If I want to get information about you, I just go to TheFacebook, type in your name, and it hopefully pulls up all the information I’d care to know about you.

MySpace is my wife… Facebook is my mistress.

Just take terrorism, for example. We have a team of more than 200 people working on counterterrorism. I mean, that’s pretty intense. That’s not like what people think about what Facebook is.

I think what we’ve found is that when you can use products with your friends and your family and the people you care about, they tend to be more engaging. I think that we’re really going to see this huge shift where a lot of industry is and products are just going to be remade to be social.
