YES! YES FUCKING YES. "I could care less" must die as an expression. I have been saying this for years. This is the only English fail that really, really, really gets my goat.
In second place is not 'hold the fort', but the fact 'alternative' has become 'alternate' in standard US English. I can't fault people on its usage because it's accepted, and therefore not a mistake, but, fuck it, 'alternate' in standard UK English is a perfectly cromulent word that implies something quite, quite different from 'alternative' and I prefer it that way.
