Im wondering when, if ever, we should use the community wiki feature which we often see on SO.

Is it even implemented in our site?

Also have a look at discussion-questions . Discussion questions and other questions which arent easy to make a common conclusion on are often tagged as Community Wiki on SO, but is it the same in our site?

The option to mark questions as community wiki became a source of confusion and pain so it was removed: What can we do to make Community Wiki better?

More times than not (many more times) community wiki was applied to compensate for poor topics that do not belong. But somewhat subjective questions can still be okay; just follow the guidelines for good subjective questions: Good Subjective, Bad Subjective.

Individual answers can still be marked community wiki. And if you really, really feel that a question must be community wiki, flag it for moderator attention. Moderators can still convert questions to community wiki. But it should be somewhat rare.

  • Thanks Robert, was I also correct that questions with many responses are automatically made CW?

    @AviD: Yes. +30 answers will make it CW. So will 10 edits by the original author, as will edits by 5 different users. Nov 30, 2010 at 23:21

As I understand it, CW can be applied to answers only.
CW on questions are only applied automatically by the system, (I think) after the question passes something like 30 answers.

I believe this now applies to SO too, though it didn't used to be like that.

  • Aha. If that is so then they changed it from back when I used to be at SO :)

I've used CW on an answer (this answer, specifically) in an effort to invite community editing of the answer. That evidently hasn't happened, so perhaps that's a sign of a bad use of CW ;-).

    Heh, true that. Truthfully, I've only seen CW used as a kind of rep-protection for controversial answers, or some kind of "altruistic" declaration. If an answer needs to get edited, it will probably get edited regardless.
