I appreciate that they publish all reviews, positive and negative, so you get a good sense of what people think of a hotel or other business. I hardly ever look at guidebooks anymore because I find tripadvisor more reliable. In contrast, I posted a moderately negative review of a hotel on Agonda (along with other positive ones) and Agonda didn't publish it. I think Tripadvisor would publish it and give the owner a chance to respond, which is much more helpful and consumer-friendly.
