MISS SNARK IS ELAINE BENES!
Yes, it appears to be true, as evidenced by this EW cover: Miss Snark, Seinfeld-savvy literary agent extraordinaire whose IQ matches her area code, is Elaine Benes.
Miss Snark's identity has been a topic of speculation lately. When she announced yesterday that she was taking a two week vacation, some Snarklings began referring to her as a "Master Rahl." Whointhehell is this Master Rahl character? I googled the name; he's a wizard? Oh good grief! This can not stand! The idea of Elaine Benes, who worked in publishing, occurred to me when references to Seinfeld began appearing. Miss Snark as Elaine Benes: I like that.
So she's off on vacation, with her fully stocked gin pail, hoping to connect with her objet d'affection, the totally sponge-worthy George Clooney. No yada yada yada about it, either ;)
