A question was recently asked, and then answered.
The orignal answer given was not quite right, and so the answerer went and edited for clarification. During the next several hours, other answers were given from other members. The original answerer has then gone and made additional edits - some of which included the answers from other members. At last count, there were 7 additional edits to the original answer, some of which clearly were intended to expand using comments/answers from other members.
Coincidentally, all the other answers have been given a down-vote.
I'm not suggesting any of this is wrong per-se - just leaves a little sour taste in my mouth. Is there any guidance on this?
