From a Comcast (cable tv) program description:
(Airdate January 9, 2007) Stabler and Benson are at odds over whom to believe in a “he said, she said” rape case involving a husband and wife (Blair Underwood, Michael Michele) in the middle of an extremely bitter child-custody dispute.
I was struck by the whom of whom to believe. Not unacceptable, but very much not what I would say or write.
Meanwhile, Stan Carey has posted about a kerfluffle on Twitter, in which various tweeters have objected strongly to the name of the Twitter feature Who to follow. Carey finds this variant entirely acceptable (and the whom variant stilted), as do I. But Business Insider thinks it’s “bad English”; GalleyCat calls it “one of the most viewed and easily overlooked grammar mistakes on the Internet”, adding that it’s “reassuring to watch a major social network struggle” with grammatical rules; Jay Rosen, who teaches journalism at NYU, believes it’s a “grammatical error”; and other Twitter users are variously bothered, disappointed, or annoyed by the phrase. Carey provides lots of quotes, with links.
He maintains that all the critics are wrong and provides a long and detailed account of the who/whom issue, with many citations of sources. Well worth reading.
Here my concern is with the choice of pronouns in the specific construction in the Comcast and Twitter examples.
