In an interesting and slightly inexplicable move, TripAdvisor has blocked Google Places from using its massive wealth of hotel and resort reviews. Now, when you search for hotels on Google, and browse around Google Maps, you will no longer see snippets from TripAdvisor.
Given Google's recent spate of Places updates, this is either a very bold or very brash move from TripAdvisor. Hotel owners will no doubt be upset at the loss of traffic -- and I'm still not quite sure what TripAdvisor gains from blocking Google. We'll update you with more information, if any emerges.
