This book is work in progress, more or less done in public. A preface here, a chapter there, bits of research, thoughts. I ask for any comment you wish to add -- good or bad or even insulting, all are welcome and helpful! What's the point of the Internet if we can't share and learn from each other? Of course it's copyrighted material, every bit of it, so please, no quotations anywhere (other than here) without my permission -- otherwise, the sky is the limit, help me out, and thanks!.
