I've written a review article focusing on David Graeber's account of Occupy Wall Street in his book - The Democracy Project. http://newsocialist.org/760-the-democracy-project-a-review
Graeber advocates "small-a anarchism" and consensus decision-making.
In what I hope is a constructively critical review, I highlight
some of the problems with this particular form of anarchism and the
model of consensus decision-making that it promotes. This is not, by the
way, an anti-anarchist rant. Class struggle anarchists would probably
agree with all but one of the critical points I make.
Among other things, I am critical of the kind of consensus decision-making advocated by Graeber and small-a anarchists, on the grounds that "There is considerable evidence that consensus decision-making provides
those who are time rich with substantially more influence than those who
are time poor because of parental responsibilities and/or paid work
commitments." I am not convinced that consensus decion-making alienates less people than the use of voting in situations where a consensus cannot be reached easily.
In the process of researching this article I read a superb account and critical evaluation of contemporary anarchism at http://isreview.org/issue/72/contemporary-anarchism. See also a socialist critique of prefigurative politics at: http://isreview.org/issue/92/reflections-prefigurative-politics.
