Here is an example of what I mean, although I don't mean to complain about that particular question but questions like this in general. This question has 6 answers and (coincidentally..?) 6 upvotes. All 6 answers have no votes at all, nor is there an accepted answer. This does not seem ideal at all for a Q&A site; the impression is that the question is unsolved and that the answers are poor. In fact most of the answers solve the asker's problem and they seem to be of roughly equal quality.
How should one deal with such a question? Should more answers be provided or existing answers revised to get the question out of stasis? Could something be changed to make such situations less likely to happen?
To me it seems that although the question got enough attention, it became "stuck" because of the answerers' egos; they don't want to vote for competing answers out of jealousy or spite.
So, as an answerer in such a question, should I upvote competing answers even though they were later and not particularly better than mine?
Thanks for any suggestions!
