We want Facebook to be one of the best places people can go to learn how to build stuff.

We talk about this concept of openness and transparency as the high-level ideal that we're moving towards at Facebook. The way that we get there is by empowering people to share and connect. The combination of those two things leads the world to become more open.

I think that there is a role that Facebook can play in empowering community leaders, to strengthen existing communities, to help build new communities, to help look out for people in their community, to help keep people safe.

There are really two core principles at play here. There's giving people a voice so that people can express their opinions. Then, there's keeping the community safe, which I think is really important. We're not gonna let people plan violence or attack each other or do bad things.

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.
