I'm just getting sick and tired of people in the crypto community dismissing projects because they're not done by one of the "ordained few".
Your criticisms of the book are indeed valid, but the obvious derision you apply when calling professional efforts such as this book and Cryptocat "amateur" is precisely the kind of behavior and attitude that keeps the state of crypto so backwards and slow, and is exactly the kind of drama you (correctly) lambasted earlier in this comment chain.
