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.

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]
