For over 150 years now, whom has been the next word about to disappear from the English language.
Hasn't happened yet. Not quite. The rules for using who or whom aren't that difficult, but most people can't be bothered. And when they do try, they often botch the job and hypercorrect.
I say let it die. Outside of famous quotes, titles, and dialogue for people who would use (rightly or wrongly) the word whom, it is archaic, commonly hypercorrected, and overly formal. The word has no place (other than the above examples) in our language.
Consider any primer or guide on the matter. The examples for where whom should be used are almost all stilted and formal. I know with whom I will speak. Who talks like that?
The few examples that aren't stuffy and convoluted--that sound like actual human speech--are all sentences that people usually use who for. Whom should I talk to about an insurance plan? Nah, people in real life just say who.
So there's no point in whom anymore. Thoughts?
