'Occupy Wall Street,' the growing, decentralized protest movement that's clashing with police in New York City, spreading across the country, and grabbing headlines across the world ... is also, somewhat unusually, a protest movement without clear demands, an identifiable leadership, or an evident organizational structure. Decisions are made by the NYC General Assembly, which Nathan Schneider describes as a horizontal, autonomous, leaderless, modified-consensus-based system with roots in anarchist thought," and thus far, the General Assembly has decided against yoking the movement to a particular set of goals, or even a particular ideology. Which is all to say that it's important to try and understand the movement on its own terms, rather than the terms most of us are used to. Here are five places to start: - The ... 'Occupy Wall Street blog', and in particular, the blog's forums. Here, for instance, is the movement's 'Declaration of the Occupation of New York City.' - Nathan Schneider's 'Occupy Wall Street FAQ'. I'd perhaps recommend this as the single best place to start. - 'Understanding the theory behind Occupy Wall Street's approach,' by Mike Konczal.
