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

I really like knowledge and reading books and just generally immersing myself in information.

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.

There's a lot of information that has been in peoples' heads and hasn't gotten onto the Internet. Even as the Web has gotten really big, there's just been this gap. So we made Quora as a general place for people to share knowledge of all kinds.

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.

Most of the stuff that people look at on Quora today was not written in the last month. You write something really good, and maybe it's the definitive answer on the Internet for the next 10 years. Maybe it's only a year, but not like a tweet, where it's only relevant for a day or a week.
