Query: Uncle Bob Could Have Done Better

A book with this title is much needed. Sadly, Uncle Bob's advice to write your UML on a napkin and later throw it away is not what we need. He is so flippant about UML that he comes across as arrogant and having much less credibility than he probably deserves. My advice to Uncle Bob: adopt a more humble attitude that will better serve your readers and write your second edition with a focus on accomplishing what the attractive title promises.
