It's like nerd catnip when you mix a deeply scientific expert, say in astrophysics, with sarcasm and cynicism. "They are so cocky it must be true. Also they're a physicist!"
"In this moment, I am euphoric. Not because of any phony god's blessing. But because, I am enlightned by my intelligence" - Aalewis

A submission is a document. A post is part of a discussion. Hence Plato diminished the role of books, favoring those contributions which are "still alive". They are two pretty different realms. A document can be highlighted because pointing to something interesting; a post is more normally a direct contribution (highlighted for such value).
