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

The PC has improved the world in just about every area you can think of. Amazing developments in communications, collaboration and efficiencies. New kinds of entertainment and social media. Access to information and the ability to give a voice people who would never have been heard.

The internet has been a boon and a curse for teenagers.

The thing is that what you see on Snapchat, that’s DJ Khaled. That’s Khaled for real. That’s Khaled.

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.

At first, I didn’t really use anything in the social network world. I was so anti-social network, which is kind of ironic. I actually first started on a chat room on my fan site.

In retrospect, I do think it’s fair to say that we were overly idealistic and focused on more of the good parts of what connecting people and giving people a voice can bring.

What really motivates people at Facebook is building stuff that they’re proud of.

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.

Particularly Instagram, people look like they have a much better life than they really do. People basically seem like they are way better-looking than they really are, and they are way happier-seeming than they really are.

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.

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.

If Jesus were here today, he wouldn’t be riding around on a donkey. He’d be taking a plane, he’d be using the media.

I particularly like Twitter, because it’s short and can be very funny and informative. It’s a little bit like having your own radio program.

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.

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.

You pick up some fans and a handful of haters along the way.

Ever since I started to get recognition I’ve picked out certain fans and reverse-stalked them.

In general, we’re a social network. I prefer that because I think it is focused on the people part of it – as opposed to some people call it social media, which I think focuses more on the content.

MySpace is my wife… Facebook is my mistress.

If there were camera phones back in the day, the biggest athletes in the world would have had a lot of explaining to do.

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.

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

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.

People want to act like they know celebrities. They want to see pictures. They want to know where you’re going. They want to hear you talk about your family.

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

My Twitter reflects what’s going on with me in my life.

I created my MySpace page in eighth grade, because that’s how all my friends talked to each other, so I made one, too. Then, all of a sudden, my friends started putting my songs on their profiles, and then their relatives, their friends in different states did.

I can’t stress to you enough how much I can relate to teens being cyberbullied. Something that helps me is looking at old videos of me and my friends from middle school, or videos of my family. I love watching funny videos of my favorite people – it really cheers me up.

I’ve been a lot more into Facebook and Twitter and Instagram, which was a bit complicated for me to understand the language of each social media, because they all talk in different ways. It’s a nice way for me to tell people I appreciate them, which I forget to do sometimes.

Social media has given us this idea that we should all have a posse of friends when in reality, if we have one or two really good friends, we are lucky.

I hate writing about personal stuff. I don’t have a Facebook page. I don’t use my Twitter account. I am familiar with both, but I don’t use them.

Getting recognized is insane. It just blows my mind. Like, someone who you don’t know at all can just be like, ‚Oh my God – are you Billie?‘

While I have never learned to use a computer, I am surrounded by family and friends who carry information to me from blogs, Facebook, Twitter, and various websites.

I have made the mistaken assumption – and I will attempt to be better at this – of thinking that because somebody is on Twitter and is attacking me that it is open season. And that is my mistake.

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.

This may sound a little bit idealistic, but when I go to my blog, my Facebook page, my Twitter account, I talk to different people from all over the world, and you see how it’s easy to establish a dialogue.

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.

You’ve gotta understand that with branding and the way things are promoted, in our day and age, your older movie stars are not reachable or accessible because they’re not a part of the whole social media world.

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.

I feel like the reason people feel like they know me is because I’m giving you myself in the music. There’s where the connection comes from; you can’t Twitter that.

It’s a juicy thing to say we’re building a phone, which is why people want to write about it. But it’s so clearly the wrong strategy for us.

I’m never on Twitter. I’m never on Instagram. And that’s not by choice: it’s just that those things never really interested me. I might post a picture here and there, but that ain’t really been my focus.

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.

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.

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.

Twitter is great to connect with fans and be transparent. I enjoy that aspect about it. But really, I’m still trying to figure it out.

Of course you can’t ‚trust‘ what people tell you on the web anymore than you can ‚trust‘ what people tell you on megaphones, postcards or in restaurants. Working out the social politics of who you can trust and why is, quite literally, what a very large part of our brain has evolved to do.

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.

I don’t like people looking at someone else’s image.

When it comes to social media, there are just times I turn off the world, you know. There are just some times you have to give yourself space to be quiet, which means you’ve got to set those phones down.

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.

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.

I love that I can talk to my fans through Twitter, to cut out the middle man. Because I’ve done interviews where my words have gotten twisted, so it’s nice to be able to have things coming straight from me.

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.

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

I was told that someone on Facebook said something ‚horrible‘ about me. Who cares? At least they’re watching the show.

Every time I say something that’s extremely truthful out loud, it literally breaks the Internet.

I don’t use Twitter for bad.

Now the playbook is we build AI tools to go find these fake accounts, find coordinated networks of inauthentic activity, and take them down; we make it much harder for anyone to advertise in ways that they shouldn’t be.

It used to be the case, like you’d switch jobs, and then maybe you wouldn’t keep in touch with all the people that you knew from that old job, just because it was too hard. But one of the things that Facebook does is it makes it really easy to just stay in touch with all these people.
