I remember, back when I started writing ktm-1, somebody mentioning the Delphi technique. At the time, I thought: that's a little far-out.
Now I think: what a helpful explanation!
My own district has been using a variant of the Delphi technique in its Budget Forums, but we seem to be past that now. I'm told that, at the last forum, someone stood up and suggested that employees take a pay cut in order to prevent further tax increases and the room burst into applause.
