http://meta.math.stackexchange.com/questions/3001/why-is-infinity-minus-infinity-a-community-wiki-question discussed whether it was appropriate for What is the result of infinity minus infinity? to have been made a Community Wiki, and the consensus was that it shouldn't have been.
A moderator then removed the Community Wiki flag from the question. However, all the answers are still Community Wiki...
Should the answers all have the Community Wiki flag removed too? Does that have any impact other than granting Rep to the answerers? And is that good enough reason to do it?
