Don't mess up your sophisticated, wonderful analyses with overusing the most complex, difficult to follow language possible. Using the best word does not always mean the most impressive (notice, I could have used erudite, but.....). Simple language allows us to speak to diverse audiences (notice, not discourse communities).
Of course, using dense, theoretically laden (perhaps better, big :)). words is sometimes essential, but only when they are the best, absolutely necessary words to use.
Manta: complex ideas, simple language.
