Social Change - Most common techniques

Following up on today's class, I thought it might be helpful if I tried to rank the collective action techniques in the contemporary U.S. repertoire in approximate order of ubiquity, in my experience.

1. Letters to Power Holders
2. Petitioning
3. Electoral campaigning
4. Demonstrating/Protesting
5. Flyering
6. Boycotting
7. Public Workshop
8. Commercials
9. Postering (including Graffiti, Wheatpasting, Stickering, etc)
10. Public holidays
11. Creating a Film

I'll be interested to see what techniques and issues you each choose to experiment with.
