I think we ought to go back to the subtitle, which explains what the book is about. David says “But I disliked the didactic style and felt the author had not thought-through at what audience it was aimed” both Graham and I were definite about the target audience as the subtitle says. Personally I prefer a didactic style, and obviously Graham does too, saying you dislike the didactic style is like saying you didn’t like the font or size of the book. Many people I have spoken to say they thought the review a bit nit-picking. The review will inevitably result in a loss of sales so Graham feels he will be out of pocket on his first self-publishing venture and we have lost his goodwill and membership.
