There is a diary on the Community Spotlight list right now which purports to analyze what we have learned from the Occupy movement.
Unfortunately, though well-written and researched, it does nothing of the kind.
The contents of that diary--and I do recommend you go read it, there is some good stuff there--illustrates the very problems that have dogged Occupy from the beginning: a poor understanding of media strategy, inherent limitations due to lack of structural governance, a muddled and unclear agenda, an overgeneralized political analysis which proposed a one-size-fits-all organizing strategy, and a failure to differentiate messages (what it was about) from strategies (how it advocated for that).
Each of the supposed "lessons" listed in the diary is not a lesson learned. It's a talking point: a message. Each is a concept that Occupy activists (presumably) hoped would be communicated to the American people.
Those five points are little case statements. Agree with them or not, it didn't take a bunch of illegal campers to convince the writer of that diary--or anyone else--whether or not they were true. The illegal occupations merely served to create a pulpit from which organizers could broadcast these talking points.
The occupations were a strategy for drawing attention to the messages; the points listed by the other diarist were the messages themselves. Got it?
Messages aren't lessons. Lessons are what you learn after doing something about what works and what doesn't. And while I'm sorry to say it, the very fact that a spokesperson for Occupy says that a group of talking points are the "lessons" of Occupy indicates that Occupy hasn't learned the real lessons springing from its experience.
Follow me beyond the terrorist fist squiggle, and I'll explain what those are.
