I've always wondered why a site like redfin, zillow, realtor.com, homeseekers, etc doesn't have a "comment" section attached to each house. Granted, it would be very difficult to maintain because you would get a bunch of trolls and flames... plus you'd get the buyer spamming it with good comments.

I know that ziprealty does have this. I have used it many times but the comments have to be approved before appearing and I have noticed if the review is very poor, they will not allow it to be posted. They also have a star-rating system in addition to comments.
