To paraphrase an old saying: "A man's got to sell his wares to survive (or be noticed, validated, empowered, etc)". There ain't nothing wrong with self-promotion in a world where every Tom, Dick and Patricia is self-publishing books on the JW experience.
On the question of the negative response of some posters on this thread, so be it. It is simplistic to portray the JWs as uniformly negative in their manner as it is to portray/ expect ex-JWs to be a uniformly receptive and positive book-buying group. We are humans (a trite but necessary observation) and as such will be varied in our outlook and comments - although to be on the receiving end of harshness may have increased the likelihood of rendering us a bit more empathic.
