How useful yelp is varies enormously if you travel. In the U.K., as an example, Yelp can feel like a wasteland - often little or no reviews, and it has nothing like the mindshare it enjoys in the US. As a result many businesses do little or nothing to keep the information on their Yelp page accurate, it’s barely even on their radar. In the US one can often use Yelp almost as a verb in a conversation (“let me Yelp us somewhere for lunch...”), this is met with blank stares in much of Europe in my experience. The lack of good data on Yelp in the U.K. has indirectly hurt other players there too, when Apple maps first launched business location information was largely drawn from Yelp, which basically seeded Apple maps with very bad information. Locations were wrong, many businesses that simply didn’t exist anymore would appear. Granted it’s been years since I last checked, but in the first few years of Apple map’s operation it was a pretty significant issue. This methodology worked great in Cupertino I guess...
