So you agree that addressing people in a post is needed/is acceptable but don't like referring them by UserIDs or emails?! - this exactly fits into my proposal to delegate to client application this "on the fly" replacement of UserIDs to Display Names (optionally, if User needs this. See previous messages in the discussion...).
See? This note is completely out of context now. And is only sent to "Public", not addressed to sazius at all.
He won't be notified, and he won't receive it in his "Messages" inbox. This is just a plain Public message that happens to have the word "sazius" in it.
