Comments are a poor substitute for collaboration. Of course they are, seeing as how they're only one form of collaboration. I wouldn't think that writing a comment to draw people's attention to some non-obvious aspect of code would count as anything but a form of collaboration. As far as I'm told, 20% projects always had to be approved by your manager. So I suspect that they are not quite as open as you are thinking. Which is why I did say, in continuation, that the 20% has been subverted at Google. From what I've heard, it hasn't always been that way.
