Where has the proper word been supplanted, though? On the internet, where speech is typically casual, full of colloquialisms? Sure, I'm annoyed by common grammar mistakes and mis-used words as much as the next guy, but until I see such mistakes and bastardizations in common use in edited material (newspapers, magazines, books, etc), then I'm not too worried. There have been different "classes" in language for as long as there have been functional divisions within societies.
