Should people be required to either accept an answer or delete the question if it has been live for a certain period of time (say 1 month) without any traffic (i.e. comment or answer)?
One question may answered again in the future, also existing answers can be reference to what they try to this question - and maybe some of them work even if they not have been accepted.
Also there is the case that many users hit one two questions, and then disappear from the site and not accept the answer that they have get.
I disagree also with this idea.
