Get a few language types together, and before long someone will bring up the great divide between the preservers and the observers of English, the "prescriptivists" and the "descriptivists" — those who'd rap your knuckles for using "snuck" versus those who might cite Anglo-Saxon cognates in its defense.
The truth is that the divide isn't nearly as great as it's made out to be. Most grammarians, lexicographers, usage experts and linguists are somewhere in between: English is always changing, but that doesn't mean anything goes.
