For the record, I have no special animus against post-grads, though I do find a lot of academic writing sloppy, elitist and complacent, even as I continue to consume it. The question of pretentious crap, for me, concerns the relationship between knowledge, authority, and communication, and then also another term - not very fashionable these days - which would be wisdom. I think Socrates provides a compelling model for non-pretentious philosophizing, mostly lost in Plato's overbearing interpretations. Another good model is Eugene Hutz's favourite philosopher, Diogenes the cynic. Or perhaps Wittgenstein. "The meaning of pretentious crap is in its use."
Given the close relationship between academic language and questions of knowledge, communication, deeper lying structures, and so on, its natural that questions of pretentious crap should - at least in their first move - turn on the university. But the question obviously doesn't stop there. I still like Rosselini's point that certain camera moves may be considered pretentious. But I can't remember the exact quote so I can't really pursue this.
