National Grammar Day, again...

John McIntyre has this to say about tomorrow's "holiday":

Beyond that, tomorrow, as always, don’t correct people’s grammar or pronunciation publicly. That’s rude. You’re allowed personal tastes and preferences, but harboring and feeding pet peeves is not healthy. Respect the dialects of English you don’t use yourself. Watch out for shibboleths; they’re everywhere, and they’ll trip you up. Learn a new word every chance you get. Honor and esteem people like Ben Zimmer and Jan Freeman and Mignon Fogarty and the merry band at Language Log and all the others who write about English with intelligence, affection, and force.
