While a positive reputation increase (received upvote, accepted answer, association bonus...) is immediately notified, why a negative score is not notified at all? If you receive some upvotes and some downvotes, then you have the notification with the sum of the increase. In case of only downvotes you do not have any notification, I note it just when I visit the Activity section in my profile.
Just to be clear, I am not against downvoting: I would like to known when someone did not like my question or answer, it could make me check if there is something wrong or something that should be clarified. In some case the downvoting comes with constructive comments and then you have the comment notification, but most cases do not fall in this scenario.
Could the "negative score" be a useful notification?
