I largely use Python, I've dabbled in C and always mean to learn more. K&R to me is the touchstone for that, just because so much of programming culture stems off of it. I find knowing these historical patterns helpful for understanding how programmers talk.
For someone like me, respectful critique of its style and decisions helps separate the good from the less-helpful. Whether Zed intended to start that discussion or not, it's still helpful.
