Well, originally, the goal was to abolish capitalism. But if you're 400 people sitting around in a park there's only so much you can do, and getting the attention of the world is a significant thing. But to expect "Occupy" to do something is a little disingenuous. Occupy is anyone who supports the movement.

There is the problem of nebulous discontent. The problem is everything is fucked up, and no single solution is big enough. But the idea the anarchists behind the original OWS had was to overthrow capitalism and replace it with various flavors of anarchism (being anarchists and all). As for what does an anarchist society look like, and how do we get there from here? I'm not entirely sure, I mean if I were, I would first have to be prescient, and I would be telling everyone who would listen about the magic formula.

You could probably get a list of demands together. But they would be all over the place, and none of them would really be enough to confront the real problems presented by the 21st century state-capitalist machinations, peak oil and climate change..
