I'm becoming convinced that comments in code are close to
useless. The first and greatest problem with comments is that
they don't alter the code's behaviour. When your code's wrong,
you can tell from its (wrong) behaviour. But when your
comments are wrong, you can only tell by comparing them to the
code. And if you're parsing the code to test the comments,
then the comments are basically worthless: you're having to
read the code as though they aren't there anyway.
Even a stale comment tells you something about the code --
you know immediately that someone made a change from the original version there, and they did it very quickly, without thinking it through (or else the comment would've been fixed, also).
If you want to talk about code maintenance, revising comments
(and documentation) is part of the job.
And I'm sorry if this sounds rude, but it's based on experience:
You really don't want to work with people who think their
fabulous code is so beautiful it doesn't need comments
