Once again I am asking, who is this person and why do they think they are qualified to tell me what's best?

Hello, I am that person. I have been programming for a long time, but I'm not trying to make any claims that my experience means I know any better. The claim is simply that modern coding practices often produce code that is difficult to navigate and that useful comments and documentation can deliver great benefits.

I do make some suggestions on how to approach those things, but they're simply suggestions based on my own experience, I'm not trying to assert any kind of absolute correct approach.
