Internet Myth #66: You don't have to be, pretend to be or attempt to sound like an expert in everything you talk about. Sometimes you just want to talk about stuff to find out if anyone there knows more about it and henceforth, you can learn a bit about it. Problem is there is a never ending army of keyboard combatants out there who prefer to tear intellectual strips off a person rather than helping you achieve some new knowledge. For long ago it was discovered Donny, that shared knowledge only serves to level the playing field - so subsequently the high and mighty possessors of knowledge are forced to admit that they aren't the sole keyholders to the secrets of the universe they heretofore believed they were and that leads to the realisation that they're not so special after all.
So it's just much easier not to tell you and/or mock your lack of knowledge. Understand now?
