When there is a community wiki question such as this one, what is the desired result?: [When do we say "Alenu L'shabe'ach"?](https://judaism.stackexchange.com/questions/4229/when-do-we-say-alenu-lshabeach)

Do we want all the people answering to edit the question and put the answers in the question itself? Or do we still want individual answers to the question? If the latter, what do we gain out of marking it as "community wiki"?
