The moderation system is flawed. Many people's answers get "collapsed" (semi-hidden) for allegedly violating rules such as Be Nice Be Respectful, when such rules clearly weren't intended to prevent their kind of answers. To see many specific examples, simply search on Quora itself for something like "Quora moderation".

I'm not sure whether Quora is too willing to collapse answers that other users complain about, or whether human moderators are biased and prefer to reject answers they disagree with, or both.

For questions that nobody will get upset about, Quora's users sometimes produce very good answers. To some extent, the Quora system probably helps to encourage that quality.

My only complaint about TripAdvisor is that it's seemingly impossible to search for and review businesses that don't fit into the categories (e.g. Hotel, car rental, etc). I wanted to review booking.com but couldn't find a way to do that.

Otherwise, I like their website.

I emailed them, asking booking.com to answer (or forward to the owner) questions about a rental apartment. The booking.com customer service rep replied with his own questions including the reservation number. I answered that I had no number because I was still trying to learn about the apartment before booking it.

A second rep replied, "Once you have made a reservation, you will find the accommodation's contact details in your confirmation email. If you require assistance in making a reservation please feel free to contact us."

I answered that with, "I must meet requirements of the people traveling with me, which is the reason I'm asking questions. So I can't decide whether to book until AFTER you answer my questions. Will you forward my questions to the owner/manager of the apartment, or not?"

I never heard from them again.
