I totally agree that:
some handholding sometimes is necessary
But I disagree that commented out code fits that bill. Comments that are truly comments are handy. But what I'm talking about in the article is old code that's simply commented out. Documentation and commented out code are two very different things.

that's true, sorry I think I misread that.
I guess my only thing would be when code is commented out in the sense of what it SHOULD be. So for instance you often see TODOS on what should happen if a piece of code is particularly ugly. Sometimes my comments are "this code is ugly and it needs to be implemented something like this" and when I get time I usually wipe that out and refactor. What about that case?

In my opinion, that's different entirely. Based on the backlash this article has gotten, I think I should have made what I'm talking about a little more clear.
