I was looking for unanswered question and I came across this https://stackoverflow.com/questions/10308511/display-mysql-using-jtable which is having an upvote to its name.
After reading the entire question I come to the comments part, to find that the user had made a silly mistake in the question, and he accepted that mistake within the comments without posting a formal answer. I did put an answer to the question so that someone as me does not stumble across the question.
I don't think reading an answer before an interesting question is a good practise (but that is my personal opinion)
There are a few questions on the site where similar problem is there. The questions get answered in the comments, rather a silly mistake is pointed out in the comment and the user accepts his mistake, and very few come back to the question which is lying without an answer.
This can be resolved if the user decide to close/mark answered to the question without an answer, and ask him to give comments. The comment could be then considered as a self-answer to the question.
P.S. I am not well versed with the tags. Please re-tag if necessary.
I hit on this example.
Windows Auth directory in IIS - web.config Permission problem (Answer by user = 3rd from last comment)
It is a legit question, which expands and crystallizes further in a series of comments, and finally gets answered in the comments. The user wants the question as answered but could not mark it down as there is no answer available to be marked answered. Once he leaves the question he never returns back to it, leaving the question unanswered.
The point is when the window of research closes, the question is left then and there. It is interesting to note that the user did return to mark his answer but could not find a way.
So! If there was a answer check mark next to the question(Suggesting to mark the question as answered), this answer would have been marked. As there were no answer to feed the design the user could have been requested to write a comment(In a new popup or somewhere). This comment would then serve as an answer.
