Votes serve as an indicator to how good a question or an answer is. Whether it be an upvote or downvote helps other/new users to get an idea about the quality of the response. It may not have a decisive effect on their actions but is still an influence.
But I have discovered that even after an edit has been made to the question, it has the same number of votes as it had before the edit. This in theory means a user can alter an answer to a point that it is no longer usable or takes it to another direction.
Is there a way to find out if that has happened? I know the edit button shows the previous edits but only few users might go into that and even then might not know which version got the highest votes. Any kind of information in this regard is welcome.
