From the Boston Globe (via Bookslut):
''Beginning a question with whom in contemporary standard English would not just be unusual, it would be bizarre," says linguist Geoffrey Pullum, coauthor of the Cambridge Grammar of the English Language. ''Insisting on whom, as some people still do when writing for print, is more and more looking like an affectation," says Pullum, who's currently a fellow at the Radcliffe Institute in Cambridge.
There are lots of language changes that I hate: 'nite', 'lite', 'kewl'...
But ditching the word 'whom'? Go for it.
