If you just work on stuff that you like and you're passionate about, you don't have to have a master plan with how things will play out.

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

I actually do think you're seeing this trend towards organizations just caring more about their brand and engaging. And so I think Home Depot will want to humanize itself. I think that's a lot of why companies are starting blogs, are just giving more insight into what's going on with them.

People at Facebook are fairly used to the press being nice to us or not nice to us.

There is a huge need and a huge opportunity to get everyone in the world connected, to give everyone a voice and to help transform society for the future. The scale of the technology and infrastructure that must be built is unprecedented, and we believe this is the most important problem we can focus on.

The real question for me is, do people have the tools that they need in order to make those decisions well? And I think that it's actually really important that Facebook continually makes it easier and easier to make those decisions... If people feel like they don't have control over how they're sharing things, then we're failing them.

If you're always under the pressure of real identity, I think that is somewhat of a burden.
