Shelley List: Did that change when I wasn't looking?

Rob Ault: If we don't use it correctly, who will?

Jennifer German: Vernacular usage.

L. L. Thrasher: If it sounds stilted, don't use it.

Yocheved Golani: It is still the grammatically correct form (always use 'whom' when the answer could be 'him' or 'her.')

Bob Allen: In real formal writing, I'd probably choose A.

John Cappelletti: Whom is correct. Who is commonly accepted and sounds less formal.

Charlotte Fox Luttrell: This one is easy! Of course, it has to be who do you want to represent you. Whom is the object of a preposition. Who is a personal pronoun. Whom is used when the prepositional phrase is used.

Mark H. Bloom: It's proper English, after all.
