It seems that Stack Overflow is getting a change and is no longer going to pin the accepted answer at the top and will now default to sorting by post score alone. In the post announcing this they posted a question asking how this should apply to other sites. Below are the choices being given and I was wondering how others thought we should tackle this.
Unpin the accepted answer on all SE sites by default and pin it back on a few sites that ask us to do so.
Keep the accepted answer pinned on all SE sites by default and unpin it on a few sites that ask us to do so.
Here are some stats about what questions would be impacted on our site. This comes from a query I got from another meta site question.
We have 8 questions with an accepted answer having a negative score and another answer with a higher score.
We have 220 questions with an answer that has a score at least 3 higher than the accepted answer.
We have 469 questions with an answer that has a higher score than the accepted answer.
