In  Chapter 5:  “Togetherness”, Weinberger writes:

because the Web is fond of taking socail structures, pounding them to bits, and letting the pieces rejoin themselves, groups –fundamental social units — are reinventing themselves in ways that challenge everyassumption about groups in the real world.

Many will take this as a drirect threat to some body of “knowledge” that purports to explain human nature to us all.  And so there is mass denial of the validity of many representations of these “reinvented” social realities.  We see it among gaurdians of “traditional learning and education”.  And we see it among the gaurdians of the “pre-Web” , “pre-Networked” Church.
