That's what it is, sort of. It's more a challenge than an invitation. People do need to read the books/source material instead of assuming they've grokked it from facebook or twitter convos. As you know, I've written light intros elsewhere on the blog... this is a high-level overview of a very complex field (which includes postmodernism). In a sense, its' impossible to give a ground level introduction, but you did a pretty good job too in your article!
