People think innovation is just having a good idea but a lot of it is just moving quickly and trying a lot of things.

So many businesses get worried about looking like they might make a mistake, they become afraid to take any risk. Companies are set up so that people judge each other on failure. I am not going to get fired if we have a bad year. Or a bad five years. I don’t have to worry about making things look good if they’re not. I can actually set up the company to create value.

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.

We are working hard to build a service that everyone, everywhere can use, whether they are a person, a company, a president or an organisation working for change

Mobile is a lot closer to TV than it is to desktop.

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.

Connectivity just can't be a privilege for people in the richest countries. We believe that connecting everyone in the world is one of the great challenges of our generation, and that's why we are happy to play whatever small part in that that we can.
