Sasha Frere-Jones, who is not a black French woman, has accepted a job with annotation start-up and ephemeral website Genius (formerly known as Rap Genius), leaving his comfortable perch as pop music critic at analog paper magazine the New Yorker. Presumably, Genius offered Frere-Jones the promise of an intellectually stimulating experience, a chance to mold editorial content in his image, and a trough of cash and stock options.
