Wobblies and Zapatistas

I strongly recommend that any proponent of democratic and decentralised revolutionary socialism (which is to say, everyone here) read Staughton Lynd & Andrej Grubacic's Wobblies and Zapatistas: Conversations on Anarchism, Marxism, and Radical History. Essentially, the book is a conversation between the two, one an anarchist with socialist leanings, the other a Marxist with anti-authoritarian leanings, on how the best hope either ideology has lies in the overlap between the two, exemplified in groups such as the Industrial Workers of the World and the Zapatista Army of National Liberation.
It's extremely valuable reading, covering the history of such groups, their actions, and the things they could've done better; how to keep a large movement from becoming authoritarian and impersonal; nonviolent revolutionary tactics; and many other topics of interest. There's also a clear but sadly brief explanation of the strategy of 'dual power' (I'm sure there are other writings on the subject; I'd be much obliged if someone would steer me towards them). Very highly recommended.
