The first time I posted on SO someone edited my question within a few minutes. I was initially annoyed/embarrassed (on other forums, a mod only edited your post if you had broken some rule) but I realised they were just improving my formatting as I had some dodgy markup in my question. That kind of thing is definitely busy work but it probably does contribute to the overall quality of the site more than you might realise. The question closing thing though I agree is annoying.
