In a column at the Foreign Affairs site (h/t The Monkey Cage), Sidney Tarrow compares Occupy Wall St. to the women's movement of the '70s, calling it a "we are here" movement whose aim is to dramatize that something is wrong in the "system of economic relations" rather than specifically to "target" capitalism. (Not sure if this is a convincing distinction.) Tarrow is a leading theorist and scholar of "social movements and contentious politics" (to quote the subtitle of one of his books) but I can't say this particular analysis bowled me over.
Btw at the same site you can find a piece by Hardt and Negri, which I haven't read. And then, if masochistic, you can go to Wash. Post and read George Will's silly column on OWS today, which I raced through and figuratively consigned to the dustbin. (Maybe even the dustbin of history.)
Update: Via here: Mayor Bloomberg is apparently planning to clear Zuccotti Park tomorrow at 7 a.m. There is a petition (see the link) that can be signed, though I doubt it will prevent Bloomberg from doing whatever he's planning to do.
Further update: The 'clean-up' has been postponed.
