On some long-standing unanswered questions there is often an answer that is probably the right answer, with more upvotes, comments including positive words & chatter. So could the system itself offer a 'soft' decision on long-standing unanswered questions by using an algorithm to determine which answer should be accepted based on various indicators.
This would be especially useful on answers to questions where the OP has left, is dormant or if nothing is accepted after a year. Perhaps a 'soft' accept would be worth half the reputation improvement of a 'hard' accept.
So should an algorithm determine the probably right answer in certain situations where the OP hasn't, can't or won't make the call?
