I try to write good questions for stackoverflow (which I'm certainly not dissing, I think it;s a great resource used properly) and I usually miss something out and have to throw in an edit. Fair enough, but it amazes me the number of people who pile in, clearly without reading what I wrote, seemingly unable to readjust when I point out "no, that's not what asked" A while back I asked a question. Let's say it was about destructors (it wasn't but for example). People started answering about constructors. Repeatedly. One of the SO editors came in and pointed out that there was plenty about constructors on SO already so he was closing the question. I rather lost it at that point, spelt out DEE-STRUCT-ORRS I was asking about. He wiped all the comments (his own included), reopened the question and today it remains unanswered. That was an extreme case of this phenomenon but stone the bladdy crows, it's not rare.
