Yeah, I find it interesting these words haven't become more mainstream though when they've been around for a while, and maybe that ship has sailed. They don't resonate? The definitions are too complex? (they often cause debates) They're not guessable? They don't shorten what you mean enough? ("it should look more like a button" isn't much longer than "it's lacking signifiers" to be worth the jargon) I see people drop "afford/affordance" into replies occasionally but most people don't know what it means and it rarely adds anything.

"Skeuomorphism" has caught on. It's not guessable but then it saves quite a few words so helps with communication. It probably got picked up by some tech news/blog sites and reached critical mass because skeuomorphism vs flat design resonates with people.
