I mentioned it partly because it's addressed in the actual article, and the specific instance I referenced is such a flagrant abuse of the guideline:
"Comments are good, but there is also a danger of over-commenting. NEVER try to explain HOW your code works in a comment: it's much better to write the code so that the _working_ is obvious, and it's a waste of time to explain badly written code."
It's almost as bad as:
// Increment i
i++;
I think we should be aiming for code that is so beautiful and simple that it doesn't require commenting; comments should be left for exceptional circumstances in which something really can't be clearly expressed in the code. But that's definitely separate from
documentation which should be separate, and at a much higher level.
