A Comment is Free video over at the Guardian. Aside from taking rhizomatic as his own concept, this is a relatively good introduction by Manuel Castells into the dynamic of protest movements, urban space and what he calls ‘cyberspace’. I’m always a little wary of the latter category hence the scare quotes.

I find it a little odd people like Castells are still trying to make sharp boundaries between urban (‘physical’) and cyber (‘non-physical’) space. The city is full of digital technology – in fact, contemporary cities are positively built on it, so why when it comes to discussing protest movements do we essentialize urban space as being pure, physical, non-digital space? Conversely, why do we see the digital as not having an effect on ‘on the ground’ protest? It patently does.
