Žižek is a joke. In the Finnish speaking world we have our own, Esa Saarinen. No substance, just empty word salad.

Gotta love Chomsky tho.

Here's a very clear, coherent and approachable talk by Zizek on the tensions within our reckonings over the "commons" (as in commonwealth) and ideology at this threshold of post-capitalism.

Zizek: A New Kind of Communism:

Compare with this excellent speech by Chomsky and its clear why Chomsky would dismiss Zizek:

Chomsky: Mind, Language & Limits of Thought

OTOH In general, stay away from Zizek's interviews as he has a distressing affect and tends towards interpersonal babbling.
