I've heard some very vague grumblings about the Dreyfus model but never worked up the motivation to actually dig into them.

But the first thing I noticed is that here's a guy writing a paper about skill progression and he hasn't encapsulated the act of writing a paper about skill progression as a progression of its own.

I suspect it's more like Novice, Advanced Beginner, Competent, Proficient, Expert, Artist, Philosopher.
