Here's an interesting take on #OccupyWallStreet from Matt Stoler (which I found via @jayrosen):
What these people are doing is building, for lack of a better word, a church of dissent. It's not a march, though marches are spinning off of the campground. It's not even a protest, really. It is a group of people, gathered together, to create a public space seeking meaning in their culture. They are asserting, together, to each other and to themselves, "we matter".
It's a fascinating analysis, worth a quick read. And the pictures are great.
