That comment was just my knee-jerk from seeing the title. Having read the sample chapter up, I found it to be exactly like you describe. I especially liked the examples of the troubles you can get yourself into. It is one thing to say "Do it like this because X," but having the "If you do it that why Y and Z can happen" drives the point home well.

I feel like after reading it I'll definitely remember the advice while I'm coding, and if I'm not following the advice at least I'll know where issues can pop up.
