I know I don't say much on this list and often I disagree with Bruce,
but I agree with most (if not all) of what he says.

Common sense, isn't. I figured out that "organic" meant that it
changes a lot, grows, if you will. But, it could've meant something
else if one were to read into it too much.

He's not talking about computer resources, he's talking about people
resources. it's difficult to process and remember method names longer
than 12 characters for most people. Similar research backs why phone
numbers aren't longer than 10 digits, and before that 7. It's easy to
remember 7 digits, that's about all the brain can do. I really think
you're reading into what he's saying too much, you're taking it
personally. He never said anything at all about "wasting resources."

I didn't think this was a stab either. Just that a lazy programmer is
a crappy programmer. And that he believes that comments are useful.

I might believe that. Tact isn't one of my strong points. Especially
since you can't read expressions or get inflections over email ;)

Jeez, chill out. That's his opinion. Just like it's my opinion that
you should chill out. /me notes this will probably end up being a
flame war, and I should've kept all my opinions on thick-skinnedness
to myself. :(

I would expect them to be fairly recent.
I think the issue here is style of coding. There are ways of writing
code that "don't require documentation." The example I can think of is
the source code to the Hacker's Diet Online. it's written using a
style of perl that's supposed to be self documenting. I found it very
difficult to read. It was not simple, it was really very complex. Not
really self-documenting in my mind. You can probably write code that
doesn't need documenting, but what if you have to do something odd
with a segment of code? How do you document, without comments, that
the API you're talking to doesn't quite behave the way it's
documented, so you have to do this block of work-around to make it
behave in a nice way?
Commenting things like //Increment count
That's a bit ridiculous, but applying a comment to a block of code as
to the reasoning behind the block, or why the block is ordered a
certain way is difficult to do without comments. At least, that's the
examples that I think of, and where I think commenting is important.
