There's a lot of back-and-forth in this discussion already and I feel like some people aren't understanding that it's not about _never_ commenting the code; it's about only commenting when it is absolutely necessary (which is actually quite rare if you're writing clean, simple code (which is, itself, quite rare!)).

I think that everybody should be required to read the chapter about commenting in "Clean Code" before contributing to this discussion. It's very java-centric and not perfect, but there is some really good insight. There is a pdf available here: http://www.tud.ttu.ee/material/kallik/JOOP/Clean_Code_-_A_Ha... (if it really helps you, consider buying a copy and supporting the authors).
