I was one of those whose initial post was a very negative review of a very popular (to some) restaurant. I had been reading the forum for some time and had friends rave about this establishment for years. We finally went and had poor food and poorer service with exorbitant prices. It was then that I decided to actually join the forum. Some took me to task over my comments but others, interestingly, confirmed similar experiences.
From what I am now reading this restaurant read the reviews and I have seen no negative comments lately.
Maybe it takes an experience like that or a run in with a Captain Bonehead to get someone motivated enough to post.
Obviously I don't agree with a requirement of X# of posts in order to post in the review or any other forums.
