That's a fair point. I went through the tutorial and totally overlooked the rest of the docs (with the exception of the ones that I needed). Even still, I think Two Scoops could be a lot more concise and spend less time focusing on why and more time focusing on how. Best practices are means to an end; if someone's reading a book about them, chances are that they're aware of the benefits of following best practices anyway and don't need the constant reminder of why portable, readable code is important.
