Language changes and is transmitted orally. Saying something is "correct" or "incorrect" is incorrect. There is "accepted among certain people" and "not accepted among certain people." Language changes through "misuse," slang, solecism, malapropism, you name it. The prigs on here need to go relax somewhere nice and peaceful and stop school-marming the rest of us peeps ("peep" has entered the vernacular now, peeps).
