Ian,
Not that Don is obligated to say so, but he's right. I'm spending my own time, money, and benefits to learn this stuff. It's not a hobby, nor is it basic. If you--like many of your colleagues at the show--want to underestimate that drive, fine by me. Yes, much of my experience has been academic and I agree you don't learn it by writing papers and essays and calculating nitrogen rates. But I know what I heard, and I questioned it because it didn't sound right to me. If you think I'm so dense as to not know what I heard, and I don't have the qualifications to even ask the questions, then I don't know how to continue this conversation. We simply aren't working on the level of mutual respect that I thought.
By the way, I'm trying to be anything but self-righteous. Nothing is wrong with challenge and response.
