I suspect that this will be the place for all your Venezuela referendum news: Radio Venezuela en vivo. They promise full coverage in multiple languages.
Otherwise, the best source for Venezuela analysis remains venezuelanalysis.com.
And I’m looking forward to reading Greg Wilpert’s Change Venezuela by Taking Power, not least for its implied polemic with John Holloway’s How to Change the World without Taking Power. Anyone serious about the issues raised by Zizek’s “Resistance is Surrender” should probably read these two books. Sadly, too much of the hoo-ha around Zizek’s article has been far from serious.
