Well my opinions on comments seem to be an extreme around
here. But read the entire thread starting at
Re (tilly) 2 (disagree): Another commenting question,
(and keep in mind that behind the scenes we were exchanging
much more pleasant /msgs) to see my personal style laid
out.
In there I lay out in quite a bit of detail my opinions on
ways in which commenting can be negative, what needs
comments, what does not, and how to comment. As you
will see reading that, the question isn't really the
density of comments. It is instead what do you comment,
why do you comment, how do you comment, and in what ways
do you make your code descriptive?
