I feel that :)

A living language is going to shift. It's inevitable. It's necessary to hold a formal version of a language for important things for sure, but for every day conversation, pedantry is just silly. Not only can we never expect everyone to know every word and every usage of every word, mistakes happen. It's a very human thing to pick up a word and never run across a formal definition for it, and that's okay.

It's easy enough to offer a formal definition if there's a misunderstanding, to get everyone on the same wavelength. But if everyone gets the intended gist, why get all het up? Communication should be fun and engaging, not a battle over semantics and usage.
