    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.

    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.

    I undid that change, which had been unnecessary.
