I'm at the protest of the clean feed system at the library in central Melbourne. I don't think I've seen a weirder mix of people. Nerds, gamers and civil rights type groups like the EFA with left wing Socialists Party sprukers everwhere. And Raelians! 
The Greens and Amnesty International both had speakers which were pretty good.  Melbourne Wireless are here also - not a bad talk either.
