If people want change, then they will find a way to get that change. So, whatever technology they may or may not have used was neither a necessary nor sufficient case for getting to the outcome that they got to, but having people who wanted change was.

It is really important for us that people understand what the strategy is and that the real approach is to make everything social, not to build a vertical approach.

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.

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.

If the original Facebook was the first five minutes [of a conversation] and the stream was the next 15, what I want to show you today is the rest-the next few hours of a deep engaging conversation.

Hollywood has nothing to do with real life.

There's a difference between being obsessed and being motivated.
