David Graeber, and it was Yale. I must have missed that conversation. Graeber is very good, and there are some others who self-identify as anarchists that are worth reading: Todd May, Saul Newman, Peter Lamborn Wilson (Hakim Bey). Plus some who don't identify specifically as anarchist but who are certainly very close to anarchism: Angela Mitropoulos, Ida Dominijanni, Mujeres Creando, Colectivo Situaciones. And others I'm forgetting at the moment.
