I guess I'm lucky. I've gotten asked a few questions and I've never had anybody be rude or pester me unduly. On the other hand, I'm not quite on the level of some of the gurus around here, so I don't attract that many questioners.
I've seen quite a bit of it going on in the general equipment forums, though. I think a lot of people want there to be a simple, easy answer, and when they learn enough to figure out that that's not the case with headphones (or anything in this world, if it comes to it) they just get discouraged and write the whole thing off. In the mean time they've asked a dozen people for detailed information and then they decide not to do anything with it (and probably buy Beats).
