This question is a follow-up the recent thread Why did my reputation suddenly increase by 1500 points? where it was explained that everyone recently got an additional $+5$ points per upvote, retroactively.
One of the comments, by @RoddyMacPhee, says
Ironically, this didn't move me one bit to my knowledge. I'm that equally liked and hated.
My reputation hasn't changed either, so I'm wondering why the update has only concerned some people - a fair question that anyone who can't see a change in their rep is going to ask themselves.
The answer is that the change happened to everyone, it's just that you don't get a notification for it.
