The biggest thing is to create a product that consumers find useful. As more and more people like something, it becomes harder and harder to have a conspiracy theory about it.

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

Yelp is in a very nice spot: local data, and especially review data, is one of the killer apps on mobile phones.

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.
