If you're always under the pressure of real identity, I think that is somewhat of a burden.

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.

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

It's, like, even in journeys like Facebook, we've had some very serious ups and downs.

You can use your real identity, or you can use phone numbers for something like WhatsApp, and pseudonyms for something like Instagram. But in any of those you're not just sharing and consuming content, you are also building relationships with people and building an understanding of people.

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.

We have these services that people love and that are drivers of data usage... and we want to work this out, so that way, it's a profitable model for our partners.

Really, who you are is defined by the people who you know - not even the people that you know, but the people you spend time with and the people that you love and the people that you work with. I guess we show your friends in your profile, but that's kind of different from the information you put in your profile.

People love photos. Photos originally weren't that big a part of the idea for Facebook, but we just found that people really like them, so we built out this functionality.

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.

I do think that we're gonna move towards this world where eventually you'll be able to capture a whole experience that you're in and be able to send that to someone.

People don't care about what someone says about you in a movie - or even what you say, right? They care about what you build. And if you can make something that makes people's life better, then that's something that's really good.
