The two go hand-in-hand. Writing articulate easy-to-read code does not mean it precludes thinking about the things you mention. You could be the best (according to your criteria) coder in the world, but if your code is unreadable, it will quite literally waste others' time. This might not seem like a big deal with a smaller project, but scale to something the size of the Linux kernel or larger and it begins to become…
I've rarely seen such poor code visually that it made it hard to follow - except in the rare case where someone commits line breaks incorrectly. Camel-case, underscores, indentation etc.. do not vary so widely as to prevent me from understanding code. What does prevent me from understanding code is 5-10 nested if blocks and insane logic checks without commenting. Have you actually experienced a coder that writes good…
What's worse is multiple nested levels of #ifdef. Not only is it hard to tell how the code flows, but you can't even be sure it's all being compiled!
I work with code like this so frequently that I actually got around to learning elisp so that I could write a function in Emacs to highlight the nested levels of #ifdef. I have a black background, so each nested level increases the brightness.
(I should really get around to pulling that code off of my computer at work and putting it up for everyone to use...)
