Thanks for Posting rf, what an eye opener !
The J.W org. have done this in many ways before, following the lead of the LDS Church, but it did not occur to me that the change in dress & grooming advice was another example of this !
I concur with your conclusions as to the difficulty with getting J.W's to adapt to Social Media, the very young could do this, but most are "in" because it is their Social Club, not for the reason of having a deep belief, or much of a faith at all I would guess. They would be embarrassed to "Witness" on-line.
The other problem they have is the very low education level of the average J.W, and their very sheeplike way of having to be directed, incapable of writing a sincere Letter themselves, they have to follow a J.W Template, that is parochial in language to me, nobody here in the U.K would start with "Dear neighbour", or claim to be a neighbour, and yet put a K.H Address, their Letters come over as a Scam. So would similar pathetic efforts on Social Media.
We have been aware for years that the JW org. was moribund, and struggling, but this is now even more stark, I may yet live long enough to see the org. go down the plughole, and simply be a footnote in History, like the other 18th Century sects that are no more.
Meanwhile the LDS Church will continue in Business.
