Query: Annoyingly excellent

This book is a self-indulgent rant, that is also poorly edited and structured. If the authors had read their own book and applied their principles to its pages, reading it would have been as much of a pleasure as using software that follows their advice.Why do I give it 5 stars?Because beneath the diatribes and soapbox oration there is a depth of experience and of thought I have not found elsewhere.The authors have considered the issue of what makes using software a pleasurable experience for the user in a depth and with a degree of insight that opened my eyes.
