I've just started reading this question which (
probably because of the many upvotes) is a community wiki question (if this is the right term for it).
Browsing through its answers, I see that all answers are marked community wiki as well (which makes sense, IMHO), except the accepted answer.
Is this because a CW question does not automatically force all answers to be CW as well? Or is it because there is not enough room on the physical page to display that it is CW as well?
Edit: I was wrong assuming that upvotes can make a question community wiki.
