Feminist philosopher Judith Butler visited some occupations, and seems very excited about them. At least that's the impression I got from reading her new article "Bodies in Alliance and the Politics of the Street". Her analysis of the square occupations from Egypt to New York with their "horizontal relations" explains not so much how the movements work, but explains what's so radical and political about camping in the streets.
I found this quite uplifting to read - I mean, all the excitement in the mass media about horizontal decision making via hand-signs and self-organisation of camps seems not so very promising if you've done it for a decade. But Butler's writing somehow makes it appear meaningful.
It might also a good read for those who somehow feel that the occupations are important, but struggle to understanding why or request that the movements should come up with a clear agenda, strategy, demands or a program.
