I'm trying to make the world a more open place by helping people connect and share.

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.

For the first time we're allowing developers who don't work at Facebook to develop applications just as if they were. That's a big deal because it means that all developers have a new way of doing business if they choose to take advantage of it. There are whole companies that are forming whose only product is a Facebook Platform application.

Facebook is all about information and helping people share it.

Think about what people are doing on Facebook today. They're keeping up with their friends and family, but they're also building an image and identity for themselves, which in a sense is their brand. They're connecting with the audience that they want to connect to. It's almost a disadvantage if you're not on it now.

Building a mission and building a business go hand-in-hand. It is true that the primary thing that makes me excited about what we're doing is the mission, but I also think, from the very beginning, we've had this healthy understanding which is that we need to do both.

Connecting everyone is going to be something that no single company can do by themselves. So I'm really glad that they and a lot of other companies are working on this.
