"You know what I found? Right in the kernel, in the heart of the operating system, I found a developer's comment that said, 'Does this belong here?' "Lok says. "What kind of confidence does that inspire? Right then I knew it was time to switch."
This kind of mentality pisses me off, and I would never want to use something managed by someone who actually believes this. Source code comments are not meant to express confidence, they're meant to express the reality of things. Leave the unrealistic confidence of how awesome a product is to the marketing guys. If there's a piece of code that seems like it could cause problems, but has been rigorously tested and there's never actually been a problem with it, and there's no better option, maybe the comment does belong there. That piece of code may never be a problem, save for one isolated case. That comment could mean the difference between days of searching and testing and a hack or a few minutes of searching and a proper fix.
For that matter, the comment may simply have been, "This function doesn't contain anything other than this one arithmetic operation. Does this belong here?" Taking comments out of context like that is what's known as a straw man in some circles.
