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.

A lot of people really like to answer questions, and they really enjoy sharing their knowledge. Especially people who have valuable knowledge.

More than a billion people use the Internet, yet only a tiny fraction contribute their knowledge to it.

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.

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

You can go to Pinterest, and they'll get to know who your friends are, but they don't get to know very much about what you've done in the past. They're starting with little information about you, and they have to do this personalization.
