What worst is that it may happen somebody is a jerk to a maker, the maker responds consequently, and the jerk feels offended and goes around saying everybody he meets how a jerk the maker is.
Even more so on the net.
I feel that we give too much importance to the communication on the net, forgetting you must know somebody personally to really know him. Yes, the net is great for keeping in touch and passing infromation, but "informatiuon" is not "knowing".
I know at least a very famous maker who's off the net because he's become so pissed off about having to bear with wannabes that he decided he'd had enough.
And he's a very warm and friendly person.
I never judge somebody as a jerk if not after first hand experience. I've found too many people said to be jerks by others who simply didn't know how to behave that, after I met them friendly and respectfully, turned out to be very fine people.
this said, no, I wouldn't buy a knife from somebody I consider a jerk, mainly due to point 3 in Blilious list

I bought a knife from a famous italian maker six months ago. I found it having what was in my opinion a minor defect (it wasn't due to sloppy workmanship, on the contrary it was the classical "job done too well"). I met him again and gave him the knife back to set the thing. I could have done it myself, but didn't want to touch the knife and preferred he fixed it.
Not only he fixed the knife for free, but invited me to come to his home, so he could give it back to me and show me his lab and share some precious tips, knowing I'm starting to make knives as a hobbist
I prefer much more remembering such fine guys rather than the jerks...
