People have really gotten comfortable not only sharing more information and different kinds, but more openly and with more people - and that social norm is just something that has evolved over time.

I'd like to show an improved product rather than just talk about things we might do.

Free basic internet access should be like dialing 911 in the US or 100 in India.

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.

Google, I think, in some ways, is more competitive and certainly is trying to build their own little version of Facebook.

While we generally believe in free speech and giving everyone as much ability to speak as possible, in practice there are lots of barriers to that, whether it's legal restrictions, technological restrictions or you can't share what you want if you don't have access to the internet.
