Here's a question that seems to have annoyed a handful of SO users.
The OP asked a question and didn't include enough code for any users to be able to give him a good answer. (All anyone did was point out that the code as posted should work.) He then came back and revealed that he had figured out the problem and explained what had really gone wrong.
Now, from my perspective, there was a real problem here, as well as a real explanation that could benefit the community. So I'm actually tempted to edit the question to reflect what the OP should have asked, and possibly even add an answer that provides the correct solution to this question.
What does the community think of this? It seems like the alternative is that the question just lies around and proves relatively useless to people, or else it gets closed. In the interest of SO being a community resource, I'd rather the question get finessed into something useful. But I also wonder whether this would be considered bad etiquette, for whatever reason.
