Great comment on a good article.

I'm reminded of back when I was studying pattern recognition for a system that would become an Expert System (this was before that term was used). I would read many articles saying what techniques would work. I had the urge to ask "But this doesn't show how you got there. Show me your discarded solutions that didn't work." I would like to see your wastebasket.

Similarly, I am inclined to someone who acts as an expert to tell me five ways that won't work.
