Lawyers and other professionals are using Quora to build their reputation and build their bonafides.

In the past, there hasn't been much reliable information about startups and small businesses available online. It's information that's really valuable, and it's information that people want to share.

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.

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.

I don't really have a writing process. I don't write at all but, honestly, I feel like it's a modern-day writing because everything is technology and if I go in there and freestyle and I keep it, I feel like I wrote that. If I go in there and fix it, it's almost like something I wrote.

Software is eating the financial services industry. We have a large addressable market for PayPal to play in.

The digital space is becoming more relevant, and people are watching a lot of stuff on the web.
