I am sorry @dang I apologize for the aggressive tone of my comment and not making a better argument without the anger. The promotion felt blatant. I let it get to me (every comment I believe at the time - and many other recent posts). It was wrong and I'm sorry.
Fwiw this was the source of the self-promotion.
