John, when you point that out, I guess it would be easier. I see your "aims". Bless your heart, and may the vids go viral in double-quick time.
I'll tell you, much of my time in the MC was spent as an instructor (of one subject or another). I am here to say that each vid is short, sweet, and to the point, with never a feeling of being "talked down to" yet very explanatory and understandable. One would be hard pressed to find ones that reached the goals of demonstration/instruction better.
