My wife alerted me last night to a terrible loss to the literary world — writer David Foster Wallace was found dead Friday night of an apparent suicide. DFW was already at 46 a giant of American literature and, even though he tended to the self-absorbed, his writing was passionate and magnetic. I always found his love of the footnote charming and amusing, even when it was distracting. I’m sad to think of all the wonderful books we’ll never see now.
