Consumers are empowered by Yelp and tools like it: before, when they had a bad experience, they didn’t have much recourse. They could fume, but often nothing else other than tell their friends.

Starting a company, your success is going to be very dependent on how you adapt. You’re going to make decisions, you’re going to make bets; most of them are going to turn out to be wrong.

A lot of what Groupon is generating is demand for something people didn’t know they wanted.

The entrepreneurs that really make it are the ones that start with an idea but are ready to change it at a moment’s notice.

I think with every successful consumer Internet business, there will be lawyers that are interested in going after your company, especially when they think that there’s a financial incentive.

Maintaining the trust of the consumer is critical to our business. We live and breathe only one thing, which is wanting to connect consumers with great local businesses, and I don’t feel we can do that if we don’t have effective ways to prevent gaming of the system.

Everyone is panicked about the transition to mobile. I don’t lose any sleep whatsoever.

In the very beginning, Yelp started as a service where we really didn’t think people would write reviews for fun. The whole concept of user-generated content was pretty nascent in 2004.

If somebody writes a review of a dry cleaner, that piece of content is not wildly viral. It’s not like a viral video that can spread across the world in a matter of minutes, so as a result, each market is almost an island unto itself.

There are so many businesses that are succeeding on Yelp that don’t pay us a dollar, and we’re really excited about that.
