SNS: Is A Blackout Coming?

With the advent of SNS systems, one of the more elusive concepts of social networking has been surface, that of the Connector Hubs; individuals central to the discemination of information and the contagion of social virii.

I’m curious if anyone is considering the potential negative effect of exposing the connectors.. i.e. when their bandwidth is consumed, will they overload bringing on the social equivalent of a blackout?
