When a question is asked, users read it and try to answer it, right ?In some questions the answers stay without a response from the author of the question.Not even an upvote or a comment saying if the answer is helpful or not.
For example this question It has been asked and answered Four day ago.The answer hasn't got any comment or upvote,it is an answer without a response from the author if the question.
I think that a new rule should be added.
That an answer must have at least 1 or 2 comments or upvotes.It musn't stay without a response.
This is just an idea,I don't want to accuse anyone.
