I'm encouraged by your optimism. Being a little cynical myself, I could just as easily have attributed his dickishness to arrogance/elitism and the missed copper to the possibility that his arrogance/elitism lead him to not even bother to finish reading the whole post before passing judgement and writing his original comment. :P He also missed the opportunity to provide further input. Not that's he's required to do so, but it's a bit disingenuous to not do so and then complain months later that you were ignored.
I do agree though that a mix of foods does seem to trump a formula, at least at our current level of understanding. And I can’t say I’d really be willing to make myself a guinea pig in this experiment at this juncture, but I’m still glad people are thinking about this issue and trying new things.
