"problem of network effect" if you accept the premises that: a) the diaspora's of the world are the solution (or at least a step in the right direction) b) the problem is that of a network effect (translation: the cold start problem)

... then one solution is for a well known, highly trafficked brand, that has nothing to lose, to implement "a".

... a.k.a.... what if someone like yahoo which still has vast reach, but is not a player in social, took something like diaspora and promoted heavily. That would solve the cold start problem.
