With the new post notices showing above posts, I am noticing an interesting discrepancy. As a user with 10,000 reputation on some sites I can see deleted answers, and they now are accompanied by a notice that says that they are hidden, and who deleted them.
When an answer was deleted regularly by users with delete privileges the notice says:
This post is hidden.
When an answer was deleted from review the notice says:
This answer is hidden.
As far as I'm aware (and see here) the term "answer" includes all answers, while the term "post" includes all answers and all questions. I don't think that the process of how an answer was deleted relates to that.
Why is an answer deleted regularly called a "post", while an answer deleted from review is called an "answer"?
Was this differentiation done deliberately? If so, to what end?
