thanks for making the destinctions. Heirarchy is dead, i agree... instead we do need to look at natural systems and model ourselves as a society by those working systems.
I think of the Native American Circle .. no man was above or below, all were heard, children knew how to sit in circle and be respectful of the space and the community. Something called a 'talking stick' was passed as everyone spoke their piece. if you had a direct response to the person speaking, it was held until your time(because the answer or question would most likely be addressed as the group collectively spoke).
At the end of speaking, one would say "A-ho!" to mean "i am complete" and the group would echo "A-ho!" to mean "you have been heard"
i sincerely believe that we are coming back to a place of community, unity and tribe. OWS *is* a gamechanger
