Three cheers to you for your comment on obscure writing.
Complex text requires time and energy to decipher it.
This seems a condescending position. Yes I am often frustrated when someone's work is very complex, but if I stop reading I will never know if their work is of value to me in my academic growth or that it is an elaborately decorated pile of dung. They insult us with their simplicity. There is a language for any discipline, there is discourse that is expected when writing for a particular audience, and there is esoteric jargon, but all this does not imply that the writer is merely creating the illusion of importance with a prescribed discourse. It may indeed be the case that for a given individual obtuse and obscure verbiage is a smoke screen for offering little to the knowledge base.
