    Idea-section and one further reference at Thomason model structure.

    I remember Mike once said on the blog somewhere that there might be some problem with Thomason's original claim that cofibrant objects in this structure are posets. I made a brief remark on this, but I can't find Mike's original comment.

    created cohomology of a category just for completeness in the course of Mike and my discussion on the blog

    I can't tell you much more... all I remember is what you said (someone said there might be a problem with it). I don't even remember who it was. (-: So it could just be a malicious rumor. I certainly haven't read the proof myself.

    The result on calculi of left fractions is especially interesting: it’s not often that we get a privileged direction in category theory!

    Of course, the asymmetry comes from ExEx, not from category theory.

    I pointed to the canonical model structure, for comparison.

    Changed the language. The previous version gives the impression that the Thomason equivalences bear no relation to categorical equivalences, when in truth they include the categorical equivalences.
