Really Simple Social Action (RSSA)

I've been thinking about the similarities and difference between syndication and social action.

Syndication solves a one-way information subscription problem. Publishers package information into feeds for aggregators to consume.

Social action demands a two-way activity collaboration problem. Doers report actions into feedbacks which produces an aggregate feed of all actions taken. Doers can act collaboratively by initiating new actions, imitating others, and refining methods.
