I'm junk but I'm still holding up this little wild bouquet:
I haven't really seen any in depth coverage of what's going on exactly with the local assemblies in Argentina, but maybe I need to look harder. I did just come across something though, Misnomer has an interesting interview up with an indymedia activist who's been helping with the Argentinian IMC, "Basically the assemblies see implementing a system of direct democracy as a way of rejecting politics."
