Recently this question caused a bit of a stir. The admitted goal of the challenge was to replace our old fibonacci question which the op felt was outdated.
The question was closed twice by high rep users holding code-golf badges, and reopened twice by regular users. It currently has two additional close votes. This is not good. This shows there is a significant content dispute over this question. Although the question has mostly died down I think it is a good idea to discuss this question on the meta.
Is the question a dupe? Should it be closed? What should we do in similar situations where a old question is being "replaced" with a newer similar question?
