Having come from aquarium boards... I have to say the level of elitism here approaches not at all what one could find at any number of reef boards, FW planted tank boards, photography boards, and some general topic boards.
I understand that the level of esoteric macross knowledge here can be daunting and not all members are friendly but if it means anything, I've seen far worse. And having been a mod myself and having to referee an online fight that devolved to the point where one member was being harassed across multiple boards and in real life... I have to say I've never seen anything here that go to such a level.
Could we be better? Sure... but I think most people here are actually happy to talk about topic X to the nth power as long as the OP is honest and sincere.
