Language Hat brings my attention to Professor David Graeber. I knew I recognised his name, but due to a shocking dereliction of duty, I note with regret that I've not read his Fragments of an Anarchist Anthropology (Prickly Paradigm Press) despite it having been sat on the TBR-pile for a long good while. I shall remedy this very soon (and endeavour to review some of the other excellent Prickly Paradigm pamphlets too). By all accounts (see, for example, his interview with Joshua Frank in Counterpunch), David is having serious problems with his bosses at Yale.
Further reading might include: Anarchism in the 21st Century an article by David Graeber and Andrej Grubacic; The New Anarchists; Give it Away - an article about the French intellectual Marcel Mauss.
