The bigger problem with crowdsourcing is that the reviews doesn&#x27;t have a calibrated baseline. As a business traveller at 150+nights&#x2F;year, my demands on a hotel are different from a leisure traveller&#x27;s. Having a nightclub in the hotel is cool if you&#x27;re going to that nightclub, but it&#x27;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&#x2F;night hotel (never mind having to deal with the noise from the nightclub). Another pet peeve of mine is to deal with clever&#x2F;funky&#x2F;cool &quot;concepts&quot;, like that one time I tried to order a drink in a all-organic bar (according to the bartender things dry and bitter can&#x27;t be sourced organically, so they only did sweet drinks).<p>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&#x27;t. It&#x27;s better with restaurants, as most people seem to agree to a much higher degree on the baseline.
