I just came across a question that had been closed by votes. The question itself seems perfectly fine to me, and I don't see any reason to close it.
The question also received an excellent answer, and there is not much to be gained by additional answers. So I don't see any "profit" by voting to re-open the question, even though I don't think the question should have been closed.
In such a situation should a vote to re-open the question be started?
(The specific question this is about $C^*$-algebras generated by one element.)
