I haven't 100% formed an opinion about them yet, but I like Anonymous from what I've heard. I'm going to look at their site.
edit: Well that was interesting. I ran into a lot of conspiracy talk which ultimately distracted me from everything about Anonymous. I looked into the phrase "New World Order" and the Venus Project, which was popularized by the second Zeitgeist film. While I share a dislike for powerful elites, I do not think that a NWO is forming.
Also, the Venus Project does articulate well a lot of things that are wrong with society. It also talks about an imaginary world that would be a lot better in a lot of detail. Even though the guy who founded it is very articulate, I'm not convinced of his world's practicality. Even if I were to admit that such a society were possible given human limitations, I think the idea of how we're supposed to get to it is absurd. And now my attention span has run out.
