What’s your take on traditional grammar vs. common usage?
Its hard to say anything new about “whom”, but it does raise a broader question: how to think about these questions. The facts are pretty plain: in formal, edited writing, whom is holding its ground. For those lawyers and professors who cant use it correctly, there is usually a copy editor who will make the change for them. At the other end of the spectrum is everyday speech, where “whom” has all but drawn down the curtain and joined the choir invisible.
