Didn't start as Anonymous, started on Reddit[1] but seeded by AdBusters[2], a liberal "anti-consumerist" outfit. They're supposed to camp out on Wall St in New York for reasons that aren't really clear at all. It's basically every delusional Redditor on /r/politics slacktivism turned into reality.

They're supposed to be protesting something about banks, bailouts, corporate personhood, jobs, and other assorted /r/politics common whining points.They apparently weren't aware that very few of the evil big banks are actually on Wall Street and that the NYSE is just a vestige of history by now. The only thing that will happen is a lot of tourists will flock down and the street will get even more clogged than it is for traffic and some arrests. People try to protest here all the time. It's nothing new. Stick the word "Anonymous" on it though and for some reason people take it to be a big deal for some reason.

This is the coming together of the most extremist Chomsky acolytes and reactionary redditards all in one with some V for Vendetta masks. Huge parody potential except for the fact that they're doing it for themselves already. Quite hilarious.

edit: this sort of reminds me of the 2005 Greenpeace attempt[3] to stop open-air trading at the International Petroleum Exchange by flooding the floor of the exchange with loud buzzers and bells, but getting beaten back bloody literally to the curb by all the angry traders. This was right around Kyoto.
