Evil Technical Reviewers
Jim Holmes (no relation) talks about the ego-deflation exercise that is 'having your book technically reviewed'. I think he's recovering well!
Sadly, I am one of those reviewers on his forthcoming book but hopefully haven't caused him too much pain. Sorry Jim. He explains a bit more about the book here.
IMHO, I think it'll be a great read - once they take into account my comments of course ;)
