I do not attend the JW meetings, and haven't since the mid-1980s. I will take your assessments that the WTS is in decline. Having been on this board for almost 9 years (wow), I have sure seen alot of newbies. And, congregations are no longer 120+ members strong, having to split congregations, etc. The Internet and information age will take away their followers and keep new ones from joining in the great numbers, and old age will take away another group.
Why my own 3 relatives that still "cling" to this cult do so, is beyond me. But, they all three find alot of fault with it. But, they equate the borg with being Jehovah, so they stay in.
