// Snip. First point removed because as was pointed out it was duped many times.
The other point was about questions that the questioner feels they can't accept an answer on.
I'm going to try and rush through this because I've just realised how much I've typed.
There are two situations when this arises, firstly when no appropriate answers have been given, and secondly when multiple answers have been given that are equally appropriate. We believe that a user's accept rate should not go down in theses situations.
We came up with a few proposals all of which would become available a certain amount of time (probably a long period) from asking a question, and assume it has answers:
The questioner should have the opportunity of passing the responsibility of accepting the answer to the community. This on the face of it sounds like just accepting the most upvoted question, and in fact would do just that! But, it wouldn't occur immediately. There would be some type of timeout until this occurred, and the question would be marked in some way (in the listings) to show that it was in this state. This may make people think twice about what is really the best answer, or perhaps to vote (up or down) when they just couldn't be bothered before.
The questioner can add a "no acceptable answers" vote to the question. Just like close/reopen votes. If enough are accumulated the system considers the question answered but without actually having an answer accepted.
The questioner can vote to merge all the answers he thinks should be accepted. If enough votes accumulate, the answers are merged. Whether this involves simply appending them together or an edit and review process to ensure duplicate content does not appear I don't know. The reputation is shared equally among the answerers.
In all cases the questioners accept rate, would stay as if they had accepted the question themselves and just like actual accepts they would have the option of changing their mind or restarting one of the above processes should new answers come through.
I wonder what your thoughts are.
