Hi, sorry, I wasn't being sarcastic at all. I meant every word sincerely and literally, including the questions. At first I thought I had no answer for "what do folks get out of Zinnser's book specifically?", but while writing my comment I discovered that I did! Sure, it wasn't very friendly, sorry for that. I was trying to help your prose. It seemed you mostly didn't like On Writing Well for its being a book, when you got much more from courses and their feedback.
