Super readable, I have a much better understanding of what people are talking about when they say "code smells". I definitely agree with Martin on the importance of having consistently formatted/understandable code, and most of his guidelines I like. I think it's useful to read this just to see the examples and where things can be improved in your own code. I skipped the chapters at the end that were extra java-focused. I read this as part of a technical book club and it generated great discussions which I think helps everyone write better code.
