I don't suppose it's particularly surprising that Susan Sontag has died at 71. Still, I'm always sad when a source of light dies. I feel about Sontag the way I feel about Jacques Derrida. I taught them. I recognized their importance. But I regard neither as one of "my" thinkers. I may have more to say later. For now, though, let me noted that I was surprised that Sontag spent some of her youth here in Tucson.
