This question already has an answer here:
There are a number of questions related to the sort order between accepted and unaccepted answers. Discussion seems to revolve around the "correctness", "ownership", and default behavior of the site. There is clearly some desire for vote-based sort order.
I couldn't find an option to enable this or a widget on the page that does it already. The cases that motivate this feature are:
- accepted answers that are really a work-around, a later unaccepted answer is a solution
- the question is time-sensitive in a way that later high-voted answers are more useful
I care less about what the OP accepted at a point in time than I do about those responses that are most useful. Over time, I'm finding votes are a better indicator of usefulness than answer-acceptance. Of course, it's not much work to scroll past the accepted answer, comments, and advertisements. Sometimes I forget and annoyingly waste some time reading something that was not useful.
To be clear, I'm not advocating a change to the default/public behavior. I'm suggesting a preference setting that enables vote-based sorting of answers.
