Some anecdotes from my experiences during this time:

I lived and worked in downtown Chicago at the time, right next to the Board of Trade. The local OWS was set up right next to it. I remember the traders had dumped out a bunch of McDonald's job applications from the window onto them below. I would walk by them everyday for months and absolutely no one was paying them attention. It was a small group of people and eventually one day just like that, they were gone.

A week or so after OWS started I was visiting NYC and we ended up at Zuccotti Park where it all started. I think there were more people selling pins, buttons, and various arts and crafts than there were actual protesters. I remember my FIL asking each one if they were trying to supplement a living or if they were purely a for-profit capitalist venture taking advantage of an opportunity at an anti-capitalist protest. I just couldn't stop laughing. He was serious.

Went to a wedding in Tulsa a few months in the whole OWS movement and their main park had an encampment of tents with signs but didn't see any activity.

The big thing I noticed was there was virtually no people of color present, no organization, was a gathering of almost entirely white (mostly young) Leftists, that like usual, failed to cobble together a coalition from other demographics and really just seemed like a spectacle.
