When you look at Google, its job is to find you the perfect web page. There are a lot of cases when you want to know something and a list of websites isn't ideal.

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.

The Internet was supposed to allow anyone to set up a web page and share their knowledge with the world. But in practice, it's too difficult and takes too long, and almost no one does it.

If you imagine your friend is recommending you content on a topic they're an expert on, they can do a really good job of that. They know what you're interested in, they know your personality, they know if you have a scientific type of mind-set or not.

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.

When we get people to log in, they end up using Quora a lot more, and we can provide a lot better experience for them. We can show them a personalized news feed; we can send them digest emails and do all this ranking to find some stuff they want to read.
