A few points which i don't expect to go down very well.
The last time there were substantial assemblyist movements were in Spain and Portugal in the 70s and 80s on the docks and in the factories. They were enterprise based rather than territorial (you could attend the assembly and put your points but only workers could vote). What kept them going, what made them live was small victories - a boss moved off a line, a compulsory hours overtime removed, a sacked mate re-instated. These small victories and the way they were organised became the default setting, they became the workers common sense, how people thought. The threat of an assembly became enough to get things done. What price some small victories now? Well, there are people whose homes are being repossessed right now, auctions of their possessions taking place right now. It's an open door - the chance to get mobile and build up real networks based in practice (no need for everyone to go) and kick past the process/content stuff that's starting to creep in. I know we're not supposed to have any demands, but lets have some results eh?
