People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people - and that social norm is just something that has evolved over time.

People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people - and that social norm is just something that has evolved over time.

By giving people the power to share, we're making the world more transparent.

We're running the company to serve more people.

When you give everyone a voice and give people power, the system usually ends up in a really good place. So, what we view our role as, is giving people that power.

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

The thing that we are trying to do at facebook, is just help people connect and communicate more efficiently.

A frustration I have is that a lot of people increasingly seem to equate an advertising business model with somehow being out of alignment with your customers. I think it's the most ridiculous concept.

A lot of people are focused on taking over the world or doing the biggest thing and getting the most users. I think part of making a difference and doing something cool is focusing intensely.

A squirrel dying in front of your house may be more relevant to your interests right now than people dying in Africa.

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

Advertising works most effectively when it's in line with what people are already trying to do. And people are trying to communicate in a certain way on Facebook - they share information with their friends, they learn about what their friends are doing - so there's really a whole new opportunity for a new type of advertising model within that.

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.

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.

Back, you know, a few generations ago, people didn't have a way to share information and express their opinions efficiently to a lot of people. But now they do. Right now, with social networks and other tools on the Internet, all of these 500 million people have a way to say what they're thinking and have their voice be heard.

Connectivity is a human right.

Connectivity just can't be a privilege for people in the richest countries. We believe that connecting everyone in the world is one of the great challenges of our generation, and that's why we are happy to play whatever small part in that that we can.

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.

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

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 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.

Facebook is uniquely positioned to answer questions that people have, like, what sushi restaurants have my friends gone to in New York lately and liked? These are queries you could potentially do with Facebook that you couldn't do with anything else, we just have to do it.

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.

Figuring out what the next big trend is tells us what we should focus on.

For the first time we're allowing developers who don't work at Facebook to develop applications just as if they were. That's a big deal because it means that all developers have a new way of doing business if they choose to take advantage of it. There are whole companies that are forming whose only product is a Facebook Platform application.

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.

Games is probably the biggest industry today that has gone really social, right. I mean, the incumbent game companies are really being disrupted and are quickly trying to become social. And you have companies like Zynga.

Hackathons are these things where just all of the Facebook engineers get together and stay up all night building things. And, I mean, usually at these hackathons, I code too, just alongside everyone.

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.

I actually do think you're seeing this trend towards organizations just caring more about their brand and engaging. And so I think Home Depot will want to humanize itself. I think that's a lot of why companies are starting blogs, are just giving more insight into what's going on with them.

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.

I always kind of see how I want things to be better, and I'm generally not happy with how things are or the level of service that we're providing for people or the quality of the teams that we built. But if you look at this objectively, we're doing so well on so many of these things. I think it's important to have gratitude for that.

I believe we have to nip Ebola in the bud before it spreads through Africa and to other countries.

I do everything on my phone as a lot of people do.

I don't have an alarm clock. If someone needs to wake me up, then I have my BlackBerry next to me.

I feel like the thing we can do is celebrate people doing great work and create more cultural momentum and awareness that this is an important thing in the world. So when the next economic crisis hits and people are talking about where to cut from the budget, science isn't the thing.

I feel that the best companies are started not because the founder wanted a company but because the founder wanted to change the world... If you decide you want to found a company, you maybe start to develop your first idea. And hire lots of workers.

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.

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 just want to make sure when I have kids, I can spend time with them. That's the whole point.

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

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.

I look at Google and think they have a strong academic culture. Elegant solutions to complex problems.

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.

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.'

I think a simple rule of business is, if you do the things that are easier first, then you can actually make a lot of progress.

I think that more flow of information, the ability to stay connected to more people makes people more effective as people. And I mean, that's true socially. It makes you have more fun, right. It feels better to be more connected to all these people. You have a richer life.

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