Even though I strongly disagree with many of his views, e-watchman's website played a large part in helping me sever my mental ties with the organization. I had heard about the child molestation beforehand, but figured it was either an exxageration or that Jehovah would deal with it eventually. However, the scriptures that e-watchman points out as applying to both the curropt Jewish priests and the modern Christian congregation, as well as his arguements against the 1914 doctrine, caused me to finally open my eyes and realize that it wasn't God's organization, that the very scriptures the GB claims to follow condemn them.
Sure, you can glean this information from many other sites, but the thing is e-watchman bases his arguements almost solely on the scriptures, and still holds to the witnesses basic beliefs, which resonated quite strongly with me back then. If I had read the same arguements from an atheist or a born-again christian, I would have probably ignored them. So, although now I absolutely detest e-watchman's articles and commentary, they do serve a valuable purpose to witnesses still heavily attached to the basic dogma of the the WTS (no trinity, no hellfire, paradise earth, 144000, etc.)
