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.

It's tough to say, exactly, what things will look like in three to five years, but there's a lot of work to do in just moving along the path that we've already set out.

Stuff like photos and events and groups - we've built pretty basic versions of those apps to start but they ended up being so much more used because of their social integrations.

If Facebook were a country, it would be the 8th most populated in the world, just ahead of Japan.

At Facebook, we're inspired by technologies that have revolutionized how people spread and consume information. We often talk about inventions like the printing press and the television - by simply making communication more efficient, they led to a complete transformation of many important parts of society. They gave more people a voice. They encouraged progress. They changed the way society was organized. They brought us closer together.

Advertising works most effectively when it's in line with what people are already trying to do.

Of course, hate speech and racism have no place on Facebook
