I use TripAdvisor mostly to review hotels and restaurants, but there is so much more a member can do with this website: one can write trip reports, upload photographs, graph all the places one's travelled to. If one is planning to travel to a specific place, this is a decent site to visit to gather up-to-date tips and advice and even warnings.

People who write reviews don't get the option of editing their reviews once they are posted. I don't like that. Also, not every hotel or restaurant in any given town is available for review.

However, I've also noticed that many disgruntled customers will get on this site to bash a particular establishment, and oftentimes a business owner has to respond to clarify negative comments. Not all the negative reviews are legitimate; people just want to gripe. Businesses do monitor this site!
