Is there a website or similar that gathers all the (public) activities in Centri Sociali and other leftist counter-cultural venues, to make it easier for an outsider to find out what's happening on a given day?
Examples for other cities might be demosphere (Many cities in France) or Kalinka (Munich), my interest is more in concerts and parties than rallies and talks.
I only skimmed the resources given in the answer to this question, but it does not seem to cover the self-organized spaces I'm interested in.
