    I finally gave Cech cohomology what should be a decent General idea section

    (I forget the history: there used to be an inadequate Idea section written long ago and then forgotten, then at some point in the past somebody rightly complained about it and I seem to remember having fixed it then, but maybe I didn’t, or not thoroughly enough, or something. Anyway.)

    The whole entry still needs more love, of course. If anyone has time and energy, please feel invited.

    (This here triggered by David Roberts asking about it here: https://plus.google.com/u/0/photos/117663015413546257905/albums/6013553739687182081/6013553742667883026?cfem=1&pid=6013553742667883026&oid=117663015413546257905)

    For others, I should explain I was not being entirely serious in that comment.

    Ah, David, I should have included an emoticon. I think you made reasonable comments. I was joking when I wrote that your attempt to extract information was old-fashioned, and that instead you should just stare at the picture.

    I have expanded a bit at Cech cohomology in the section abelian Cech cohomology – Definition

    [ hm, the software is behaving funny, clicking on that link, at least on my system, takes one to the wrong subsection. The correct subsection is being highlighted, though. Strange]
