I'm not so sure. It seems more like astrology, in that it's vague enough to apply to someone who wants to think of themselves as an absent-minded genius, than thesis material. Apply the context of programming and you've got a sure hit, albeit lacking real content.
You could extract a list of traits from these posts and make a survey (agree, strongly agree, etc.), then score it. That would give a clear scale and quantfy the fortune-teller aspect. Psych is harder than math, after all, since the answers are never clear/simple. :)
