Go ask any random person in a restaurant or spa where they heard about that business. What do you think most answers will be? Yelp or Foursquare? Foursquare is not built as a search engine, first, while Yelp is. You check-in first via Foursquare, then you can explore other places, while in Yelp, you're prompted to search for a place. If you're talking about simply discovering random places, then perhaps Foursquare is the winner, but that market is nowhere near as big as searching for a place. The latter is about capturing intent while the first is about generating interest.
