No, if they don't see the question again they'll never know you updated it.
I am nearly sure they don't
Nope, nope and nope.
Nope unfortunately. Maybe one day
No. You would have to update each answer individually or like their opinion for them to get a notification
Only if it comes up on the live feed while they are viewing but No direct notification.
They do not.
No, i don't think they do, unless you answer to every reply the others have given saying 'hey i updated my question pls check it again', otherwise they won't get any notification when you do
