Who are the Free Users?

The early socialists found themselves in a position somewhat like the free users movement today: with plenty of ideas for a better world, but little strength to put behind those ideas. Karl Marx had a point about that: ideas don't triumph simply because they are sound. They need to express the needs and viewpoints of enough people to fuel a revolution.

The socialist movement found it's strength in organizing the working class. Where are the people we can mobilize for user freedom? Among the techies, scientists, librarians, teachers? The file sharing youth? The unions, the environmental movement? Developing countries fighting for their right to use their knowledge?

What kind of political action are these groups capable of? How do we knit them all together? Bring along your experience with working for user freedom in different contexts for this discussion on political strategy.
