I recently answered a question here. 2 minutes later, another person answered the question.
I noticed that after visiting the question a few more times, my answer seemed to switch with the other answer and vice-versa a couple of times. Both of our answers have 0 score, there are no other answers, and mine answered first.
My question is, how do you determine the order of answers with the same score? I would have thought that it is based on when the answers were written, but since these answers are switching, it can't be the case.
