This question already has an answer here:
Most downvoters quickly express their opinion, navigate away, and never come back. That's an issue because even though a poor answer or question has been edited for the better, downvotes are rarely reverted. If the view traffic wasn't dropping as the question ages, the community would probably counterbalance the votes, but that isn't the case.
Perhaps users should get notified if an answer/question they downvoted gets edited?
Obviously, we would have to avoid getting too many notifications when multiple edits occur.
Here's a few ideas:
- Send notifications if the question/answer gets modified, but only within a limited timeframe
- Implement an "ignore future notifications for that answer/question" feature
- Implement a "notify me if that question/answer gets edited" feature, which would allow users to track a question/answer's state (checked by default?) rather than forcing notifications.
I think that having some mechanism in place to encourage people to review their downvotes would make that measure more accurate in general.
