" there are absolutely better social networks out there…"
So very true ! Long before I woke up and left, I said to a JW "I get a better welcome in so-and-so than I do in the K.H. In the place I referred to, everybody said "hello" and chatted and asked after my welfare, some in the K.H could not even be arsed to say "Good Morning".
The trouble is, you don't realise this fully until you leave.
Tinkering at the edges of the various things that are systemically wrong with J.W org, be it DFing or whatever, will not stop the steady flow of those leaving IMO.
