Al Jazeera's The Stream did an episode on "the anarchist movement"! I've read Crispin's book. It was surprisingly compelling for a book on political philosophy. It was so good I will probably read it again. I've also read the first third of Cindy's book. I remember it being surprisingly boring for a book about anarchism. I may have to give it another try.
