Challenge of Dunbar Number 150---could collectivis

<Free> is pretty much like <the long tail>, entailed as much criticism as praise, I guess this is what Chris expected...
the content itself has nothing particular new or disruptive, what strike me most is the network theory on Collectivist's doom Dunbar number 150. as we grow up with boring communism doctrinal education on collectivism and the future rosy life that we work as we want, the trade-off is no longer financial compensation but mental satisfaction. as Kropotkin's <mutual aid: a factor of evolution> claimed.
the hard truth is no matter how hard we try, how nice we are, the social bond that police mutual aid start to fray at the size of 150. a empirically doomed number to survive the rule.
should the incoming freeium economics could potentially challenge the hard truth? should the information abundance once again overthrow the traditional scarcity economics? these are the questions I would like to explore.
