Really? I think it's an apt comparison, given the limitations of the knife world. Your 2nd to last paragraph is a good description of both, although I wouldn't say 'prey,' because poor and ignorant people genuinely WANT what they're both selling... As to how clueless I am, all I can say is
Do you remember when Mark first joined the boards? I remember him as seeming to be a decent guy, had his own small retail operation, and seemed to be genuinely interested in the how and the why of steel, sharpening, etc. I don't believe Mark started with deceit in his heart, like he wanted to use our collective knowledge to further his career... Maybe he was a con artist from the beginning and maybe I'm naive, but I prefer to believe that he was a genuine enthusiast who happened to be in a position to make a profit, and so he did. If anyone's to blame, I'd point my finger at the consumer, who has continued to reward him for questionable behavior.
