Interaction with fans is'nt part of their job description. I'm sure if they had some clause incentive ".0005% pay increase after 500 posts", or something, that might be different. It comes down to the predilection of the individuals on the team. You have natural polemists like JE, but he was one of those rare exceptions. He was really more interested in presenting what he thought to be unassailable arguments, and then defending them. He simply enjoyed arguing... I mention him specifically since he, more than anyone else, was responsible for the "mood" shall we say of the old Interplay Boards, in which the fans came to expect this free flow, this interchange, of information. Maybe people expected that to carry on here, even though he's not a part of Obsidian. *shrugs*
As to why others around here choose/chose not to speak up, that's their business.
Sports/Rock Star is'nt really that accurate of an analogy. Novelist might be better. Or ship in the bottle maker... har har
Introversion, patience levels(1000s of worthless posts to wade through), work load(no time),... these folks have plenty of reasons for not posting. And it's certainly not recreational for them(cept for JE), since, unlike fans, they have to be carefull about what they type.
