The great thing that guys like Facebook's Mark Zuckerberg and the Google guys have in common is they treat their technology like it's art and I suppose in the hands of virtuosos like them it is.

Social cohesion was built into language long before Facebook and LinkedIn and Twitter - we're tribal by nature. Tribes today aren't the same as tribes thousand of years ago: It isn't just religious tribes or ethnic tribes now: It's sports fans it's communities it's geography.

No one has done a study on this as far as I can tell but I think Facebook might be the first place where a large number of people have come out. We didn't create that - society was generally ready for that. I think this is just part of the general trend that we talked about about society being more open and I think that's good.

The rise of Google the rise of Facebook the rise of Apple I think are proof that there is a place for computer science as something that solves problems that people face every day.

As social media is less about technology and more about relationship building we are starting to see more women have a heavy influence if not dominant role in the social media space. It's no wonder that Facebook is being run in part by chief operating officer Sheryl Sandberg.

I think peace should be done not only among governments but among people. It was impossible before the Facebook.

We can't blame children for occupying themselves with Facebook rather than playing in the mud. Our society doesn't put a priority on connecting with nature. In fact too often we tell them it's dirty and dangerous.

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.

Facebook is at the forefront. It's the company that can fundamentally change the way information is being exchanged and processed. It can be the basis for artificial intelligence to develop over time.

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 have no idea how to get in touch with anyone anymore. Everyone it seems has a home phone a cell phone a regular e-mail account a Facebook account a Twitter account and a Web site. Some of them also have a Google Voice number. There are the sentimental few who still have fax machines.

It would be incredibly presumptuous and self-serving of me to believe that Facebook was the end of history. The only way it could possibly be the end of history is if it becomes some sort of artificial super intelligence that takes over the world.

Facebook now is mostly about people you know. In the future it could be about people you know less but are more important.

I don't need to go onto Facebook and pretend to have friends I've never even met. To my mind that kind of destroys the meaning of the word 'friend.' I take exception to that. Because I value and respect friendship.

The fear of the never-ending onslaught of gizmos and gadgets is nothing new. The radio the telephone Facebook - each of these inventions changed the world. Each of them scared the heck out of an older generation. And each of them was invented by people who were in their 20s.

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.

I can't say I'm not grateful to have journalists writing about me as a genius. But I know it's not true. I'm not confused. I understand that success comes through a lot of failure and a lot of very embarrassing failure. People want to create the next Facebook but they are too afraid to create the next Facemash.

My career was full of struggles and dreams disappointments and peaks and valleys. But there was no Twitter no Facebook or TMZ. Young actors could make mistakes and not become the focus of tabloids.

People spend hours constantly checking and tweeting and Facebooking. And it's cool to check up on your friends and see what's going on in the world but it's not cool to spend five hours of your day on the computer looking at the Internet.

Even in high school I had friends that I didn't know were gay until years later. I'd find out on Facebook or something and be like 'Oh that explains some things ' or 'Wow no wonder they were so cool.'

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 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.

My two daughters live on Facebook and social media is their mode of communication.

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