Graham,
Couple of honest but well meant questions.
1. Do you have a publisher?
2. Has anyone commented on your writing style with brutal frankness?
These are based on my reading experience rather than my own pitiful writing skills, and none as a literary critic. Like Kevin (Perkins), I hack away, enjoy myself attempting to express a few ideas, pleased to stir some thinking, glad that someone will read the result but having no pretentions that it is of literary value. This is only my own perception but this writing comes over to me as stream of consciousness rather than structured, lightly laced with purple prose. That should get some bites ;o)
Good luck!
