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.

I generally think if you do good things for people in the world, that comes back and you benefit from it over time.

The companies that work are the ones that people really care about and have a vision for the world so do something you like.

I personally don't invest in a lot of companies because I think it would be a conflict of interest and Facebook doesn't typically either.

You can be so bad at so many things... and as long as you stay focused on how you're providing value to your users and customers, and you have something that is unique and valuable... you get through all that stuff.

Betting completely on HTML5 is one of the, if not THE biggest strategic mistake we've made.

In addition to building better products, a more open world will also encourage businesses to engage with their customers directly and authentically. More than four million businesses have Pages on Facebook that they use to have a dialogue with their customers. We expect this trend to grow as well.
