No one has done a study on this, as far as I can tell, but I think Facebook might be the first place where a large number of people have come out. We didn't create that - society was generally ready for that. I think this is just part of the general trend that we talked about, about society being more open, and I think that's good.

The young people are the most active and vital force in society. They are the most eager to learn and the least conservative in their thinking. This is especially so in the era of socialism.

I like going to Burning Man, for example. An environment where people can try new things. I think as technologists we should have some safe places where we can try out new things and figure out the effect on society. What's the effect on people, without having to deploy it to the whole world.

This sign I give you: every people speaks its tongue of good and evil, which the neighbor does not understand. It has invented its own language of customs and rights.

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.

You're working because you want to change the world. You want to make it better. Why isn't the company that you work for, worthy not just of your time but your money as well? I mean, but we don't have a concept of that. That's not how we think about companies, and I think it's sad, because companies are most of our effort. They're where most of people's time is, where a lot of the money is, and so I think I'd like for us to help out more than we are.
