It strikes me that the interesting problem to solve here is the legal liability.

Even if you're perfectly in the clear - protected by the first amendment - that doesn't stop people from attempting to sue you. So I wonder how they deal with that risk.

Incorporate. Pay out high salaries.

People are running out of good ideas for products.

I thought it was funny and potentially useful. I often use Yelp, not to find a great restaurant, but to avoid a terrible one.
