Recently, there's been a pop-up about review queues:
It is extremely annoying, as I believe other people can agree. It does a lot more to distract and aggravate people than it does to inform them, and it acts against one of the keys to SE's success: a clean UI.
I for one do not want the site bugging me to death every other day, by covering things up and being distracting, about features that I will most likely never use - or about ones that are not new to me and that haven't changed. This makes it harder and much more stressful to do things with the features that I do use, and many people feel the same way.
Can we please remove this immediately, and can we please avoid these sorts of "Got it" pop-ups in the future? I don't remember ever meeting a user, here or in real life, who thought well of these things.
