If you want to be free, or you want to preserve freedom for people, you both need to have laws that make it so people have freedom of speech and all the freedoms that they need. You also need to have an open governance system where people can vote and people have representation.

Almost any mistake you can make in running a company, I've probably made

There are many machines throughout history that were built to do something better than a human can.

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.

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.

This is our commitment to users and the people who use our service, is that Facebook's a free service. It's free now. It will always be free. We make money through having advertisements and things like that.
