The bigger problem with crowdsourcing is that the reviews doesn't have a calibrated baseline. As a business traveller at 150+nights/year, my demands on a hotel are different from a leisure traveller's. Having a nightclub in the hotel is cool if you're going to that nightclub, but it's a special kind of hell to get back from a long day and have to fight your way through a nightclub line to get into your $600/night hotel (never mind having to deal with the noise from the nightclub). Another pet peeve of mine is to deal with clever/funky/cool "concepts", like that one time I tried to order a drink in a all-organic bar (according to the bartender things dry and bitter can't be sourced organically, so they only did sweet drinks). Trip Advisor (most relevant for hotels) and Yelp is supremely bad for surfacing the aspects I care about from the depths of things I don't. It's better with restaurants, as most people seem to agree to a much higher degree on the baseline.
