This could potentially completely change the answer. We should be given the opportunity to review it and if necessary comment or change our minds about accepting it. Of course we can do that now but there are no edit notifications so we either have to review all our accepted answers periodically or get lucky and find it.
I recently had this exact situation happen in reverse. I answered a question, which was then substantially edited. My answer was subsequently down voted because it was a poor answer to the edited (and completely different!) question.
This is pretty harsh, since I don't see that I did anything wrong, but I can see why a viewer faced with the current question would come to the negative decision.
I think some way of linking specific versions of answers to versions of questions would be helpful, or at least some sort of visual cue indicating the edits have taken place.
This is actually a really good idea. I forget, are edits to your question/answers notified? Because, if they aren't, they should be as well for much the same reason.
It's a good idea, but I'd add a few things:
- Notify on changes on every question/answer you have voted upon,
- but only if the change was over 50% of the state when you voted/accepted the question/answer.
May be it would still mean a lot of noise, but if this is implemented, even if it's only for accepted answers, the second point should be added (with maybe a lower threshold).
Doesn't the "Recent Activity" already do this? I believe that it shows any posts (answers or questions) that have been edited on any of your questions or your answer.
It's maybe not an in your face notification, but I kinda like it better.
But I could be wrong.
