It's possible -- I'm not a regular reader of his blog, and thus might be missing stylistic cues, or other occluded methods of admitting a failing. The only thing I read him admit to is that he's less sure of himself than before. Likewise, "Right now I think conflict theory is probably a less helpful way of viewing the world in general than mistake theory" doesn't quite express the idea that "these two theories actually address vastly differing questions that I and the rest of 'respectable' society have been conditioned to conflate". (edit) To clarify: how to obtain power (conflict theory) vs how to effectively wield power (mistake theory)
