Thank you very much for the points you raise. I completely agree with everything you say in your first paragraph.

As you say "to work, it has to be simple." It's simple to me, but only because I've been "test-driving" it for a decade.

Absolutely, I have a ways to go in articulating it, so that it is "immediately understandable and usable for everyone." But my hope is to get to that point. Your points are crucial to a road map to get there.. So again, thank you!
