It is easy to spot (most of) the experienced coders from the newbie coders. Any programmer who has written his salt worth of code knows that comments can save your ass. Come back to some code ten years later and you can sit there staring at a bit of code no bigger than your thumb wondering what the hell it does and often it doesn't become clear until you shove some test samples down its interface and see the result. Whereas a simple comment is all it would have taken to clear it up from the start. People who argue that comments can get out of whack with code, well, of course they can, but that's no excuse. That's just a failure on the programmers part to always update comments when the code changes.
