Nice post, Tal. Even after all these years, I still have to pause with 'farther' and 'further.' My biggest pet peeve, though, is with another form of misused grammar. I cringe when I hear or read nouns being used improperly as verbs - 'impact,' 'partner,' 'party' and so on. I'm just an old fogey, I guess.
Thanks for the link, Tal.
