What is the rationale behind making the question a community wiki with list questions? Why should this question require editing by new users?
And why should the answers be community wikis? I might expect all answers to be edited into one big answer as a list, but that doesn't appear to be common practice. Do other people really edit your answer to a list question?
What's behind this community-wiki thing? Does it make sense? I've never seen a community-wiki question on this website that seemed to profit from it, but perhaps I've missed or forgotten one.
