There are social restrictions where someone could be suppressing someone else's freedom to express themselves.

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

If you live in an area where there is not a good school, the internet may be the best way to get access to a lot of education material. The same is true if there is not a good doctor - the internet may be the best way to get access to health.

We should have a society that measures progress not just by economic metrics like GDP, but by how many of us have a role we find the meaningful. We should explore ideas like universal basic income to make sure everyone has a cushion to try new ideas.

The world isn't set up equally, and the first billion people using Facebook have way more money than the rest of the world combined.

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.
