Quotes from Adam D'Angelo

I think as more people use the phones to access the Internet, they have a lot less patience for trying to find things on the search engines. That is because you need to figure a lot of things out for search to work.

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.

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.

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

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.

Wikipedia is kind of extreme, where a very, very small group of people contribute pretty much everything.

Focus on the long term, and always do what's right to grow the company and not make short-term decisions. And outlast everyone one.

We want Quora to last forever, and in order to last forever, it's going to need to have revenue. One of the best things about ads is that you don't need to exclude anyone.

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.

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

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

We're more interested in someone writing a really great answer that's going to be read by thousands or tens of thousands of people over the next few years as it stays on Quora and as it gets distributed on the Internet.

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

I think a lot of what the iPad app is going to be used for is just reading the best content on Quora. It really helps the whole system run because people who are writing answers can get this very wide distribution to a large audience of readers.

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.

The area we define as what Quora's good at is long-form text that's useful over time, and where you care about who wrote the text. Not that you need to be friends with them, just that they're someone trustworthy.

When you look at Yahoo Answers, there can be a lot of garbage. But if you're careful about the rules and supporting good contributions, over time you can get better and better, like Wikipedia.

We started off by inviting our friends to use Quora, and then they invited their friends, and it just grew from there.

In 2007 I was at Facebook, and we looked at some of the social networks in Asia, and they were full of games.

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.

I've really enjoyed starting Quora from the beginning. It's really nice to have a new start to things.

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.

Blogs are easy to start, but unless the author is famous, it takes years to build a following.
