Makes me think back to the terribad philosophy classes (at least the softer, less mathy ones - the pure logic ones were fine) I had to sit through in college. My trick back then: whenever I read a paper/essay/book on any topic (particularly metaphysics), I always kept an informal tally of the percentage of argument devoted to arguing that someone else's definition of a term is "wrong." Generally speaking, that percentage is inversely proportional to the overall quality and relevance of the paper - there's no point listening to people argue whether God exists or not if they're merely redefining "God" turn-by-turn until they each prove their point!
This obsession with arguing over definitions and attempting to answer ill-formed questions isn't limited to philosophy, though, it's quite rampant throughout most of the humanities world and even comes up more often than it should in sociology and psychology. Which is a shame - those are both fields where tangible advancements with real world consequences could probably be made, but mired as they are in soft thinking, where everyone can be right (or at least present arguments obscure or pointless enough to dodge criticism), they have a very long way to go. At least psychology is starting to give way to cognitive science, which may pick up some of the slack; I have yet to see any sign of future improvement in sociology.
