I agree with Ninja,
Though my current opinion is that Robert King is a bit of a nut-case, I have to admit that his website did help me to get my feet wet as well.
I originally viewed JWD back in about 2001. Later in 2005 I went to the e-watchman site. I never participated there, but I read every commentary he had. For me it was an easy step to take. Robert King disagrees with the WT, but wants everyone to remain a J-dub until Jehovah returns to 'cleanse' his organization of all the problems and mistakes that has occurred with in the WT corp. That kind of thinking can be comforting to the average j-dub. You get to acknowledge all the problems with 'jehovahs organization'™ and yet you can keep all the fuzzy feelings you get from believing you will live forever in a fantasy paradise earth.
It was the e-watchman site, that acted as a 'stepping stone' in bringing me back to JWD in Dec of 2005.
So in reality, I do think e-watchman does serve a purpose in the grander scheme of things.(at least for me it was helpful)
