"Best Answer" feature discourages community involvement
Admins (and possibly anyone?) can mark "Yes" or "No" to "Did you answer the question?" which is listed below each comment. I chose "Yes" to see what would happen, which was:
(a) My comment was immediately pulled to the top--i.e., suddenly it was out of order, which means it was no longer in context with the other responses and didn't make sense.
(b) A green "Accepted Answer" box was added next to my comment.
(c) A bold "Best Answers" heading was added above my comment.
Pulling the comment out and moving it to the top removes it from its context, which makes some comments nonsensical. In addition, I'm not sure why the comment is marked as both the "best" and an "accepted" answer.
Since the Community is a community forum, where the idea is to collaborate on answers when necessary, it's often the case that multiple people bring a piece of the answer to the table; there should be no "Best Answer," as that adds the uncomfortable element of ranking responses (and, by extension, people). Being able to "like" an answer should be validation enough.
I strongly suggest getting rid of the "best answer"/"accepted answer" feature (if the feature is kept, we need to only have those "best" answers copied to the top, not moved, so we at least avoid taking comments out of context).
