What is the intention of 'community wiki' questions?
Probably a bit of a noob question, but I can't quite see what service the 'community wiki' question provides.
I can understand that it allows others to edit your question. (As per the 'This post is a wiki. Anyone with karma >750 is welcome to improve it.' text). It creates an optional lower bar; normally a user would have to have 2000 karma to edit a post. I also see that answers can be made into 'community wiki' answers.
But then what?
The feature isn't really documented as far as I can tell, and where other features usually have obvious functionality this one seems a little lost.
Is the idea that 'communities' ie all the members of the site, will have certain pages that they wish to make wiki pages?
How can users see these pages? Is there a filter that can be applied somehow? Perhaps wiki questions should be marked with a small graphic on the main page. Perhaps wiki questions (and or wiki answers) should float to the top of the main page.
I'm not sure because I'm not sure what it's designed to do.
