Specifically I am talking about this question, the answer to which is getting a lot of suggested edits from new users along with some from veteran users.
The question's nature is kind of too-broad (asking to identify over 100 characters) which is why I can partially understand the community effort.
But the OP hasn't marked his/her question as Community Wiki.
Usually when I see people crossing a line on editing which really should be another answer, I reject it. But I am confused about this one. I have already approved edits to the existing answer and deleted one answer which went their own way instead of editing it in the existing answer.
So in this situation, what is the optimal course? Should we let the community make edits to fill in the gaps? Should we reject those edits and tell the editors to post their own answers? Should we make the answer Community Wiki? Or taking drastic measures, should we close the Question as too broad?
