As a user though, I find it extremely annoying when I'm trying to find out how old an article is and can't find a date anywhere on the page.

Yeah, if it doesn't have a date, that's (to me) a much stronger negative signal than an old date. If its old, I can take that into account (and, particularly, I can properly contextualize it and understand what it must not have considered because of timing.)

If it doesn't have a date, I can't contextualize it, and its value drops.
