Searched, no duplicates I could find on this proposal. The editing an answer without showing that the question was 'edited' is a nice feature of SO. Unfortunately, sometimes answers are written incomplete either intentionally or unintentionally. Therefore, the answerer goes out obtains more information and completes the question fully. Meanwhile, the answer has been downvoted. Sometimes there is a comment that the answer is missing something, which the answerer already noticed and yet it is downvoted. Even after editing and the problem is fixed, the original downvoter does not go back and re-up the vote.
So, is there any interest in preventing upvoting/downvoting for at least the first five minutes? (edit grace period)
Edit1: Everyone thinks this is a FGITW problem.. it's not.
