On Quora, you're not answering questions because you want to get points or because you have nothing else to do.

The more questions and answers we get, the more useful Quora is.

Our goal is to build this up as a knowledge base that anyone can look at. We're not just interested in people answering their friends' one-off questions.

When companies get big, they slow down. They're not as exciting. If you want to get something done, it takes a lot of time and a lot of meetings.

Anything you want to know, you go to Quora and get it. And at the same time, give people a platform that is easy to use for sharing the knowledge.

Questions and answers is a big space, and there are lots of possible systems that you can create for different goals.
