The title of a Stack Overflow question is shown quite prominently, e.g. it is shown as the first line in a Google search result. So when I look for answers to a question, I skim over the titles to figure out if a post may answer my question. Unfortunately, it happens quite often that I get tricked by a title: The title is a general question, but the question text is actually on a very specific sub-aspect of the question which doesn't apply to me.
What should I do in this case?
My first idea to make SO a better place and to edit the question title, e.g. by adding the most relevant precondition of the question in the title. However, these edits tend to get rejected as too minor. I do check if the question can be improved, but often there is nothing to fix in the body. The real problem is a mismatch between title and body, and it is quite clear that the title should be modified in this case. But this leads to forcibly small changes. Given the importance of the title, can be an improvement of the title really too minor?
I'm aware that I can also vote -1 on the question because it "was not useful" for me. I'd prefer to be constructive though.
