Simon started the forum in 2000 because he had questions about Watchtower doctrine and the answers he was receiving back then were unclear, unsatisfying, or even absent. He was still a JW in good standing then. More like-minded people who had questions or doubts joined on, and pretty soon it becamse clear to the earliest posters including Simon that there were no good answers to some of the questions about the WTS.
Some really good and thoughtful posters joined and put up some very detailed and convincing discussion of Watchtower-related issues. Before I joined in early 2001, it was clear that this website was primarily critical of the Watchtower Society, and this site confirmed a lot of the doubts I had plus added a few new ones. Then in years shortly after, the UN/NGO scandal broke primarily on this website and this was the last straw for a lot of doubters who had been lurking at this site. Also there was a lot of discussion in 2002 about the pedophilia scandal which broke on news programs in several countries including the USA, Britain and Australia. (It was Dateline NBC in the USA.)
