That's the kicker though: how bad is "good enough"? If I ask Google for a donut shop and can pick the one that has devil's food chocolate donuts, who cares if Yelp would've given me better reviews; the basic information is there in front of me, and I don't have to install an app or deal with popups.

I stopped using Yelp the minute they made their mobile site unusable in a pinch while pulled over on the side of the road. It doesn't matter how good the content is if I don't have the time to jump through their hoops.
