I was going to argue whether or not that's true, but then realized that that's not the point. I certainly tangentialized enough in my initial post.

You may perhaps be correct in your assumptions about the point of the article. I have not read any more than the snippet posted above.

However, in reference to that, Bohemians, of whom I think Beatniks would be a subculture (sub-subculture?), existed before Beatniks did. It would therefore be possible for the literature to focus some of them into the more cohesive Beatnik culture. However, I'd argue that there were no cyberpunk-inspired poseurs before cyberpunk hit, and it would therefore be hard to focus a nonexistant entity into something else.

Edit: Dammit! I did it anyway!
