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

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

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.

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.

Maintaining the trust of the consumer is critical to our business

Choose something you are passionate about - or a pain point that has affected you and that you feel really needs to be changed.

Theres simply anger over the accountability that Yelp brings and also this feeling of powerlessness because so much power is now being put in the hands of the consumer. But the important thing that gets lost with some of these business owners who are very upset with us is its the whole picture that counts.
