Always with the half-excuses for people with technical ability/track record. "Well he comes off as kind of rude, buut he kind of knows what he's doing so the arrogance is maybe warranted". Just goes to show that technical ability and dealing with people even in a technical setting are two very different things. I guess that is the reward for a technical track record? Being half-excused for lording it over other people?
Disclaimer: I know nothing about Cox' online personality. I'm just addressing how people react to rude (or whatever the intent is) technical people.
