The Internet supports many virtual communities, and it is arguable that its
support for communities is its greatest success. All virtual communities d
epend on their network for communication and any shortcomings in the networ
k, especially shortcomings relative to the natural communication that takes
place in real-world communities, will affect the community supported by th
e network. An analysis of the relationship between the supporting network a
nd the supported community is presented. The analysis is cybernetic in that
it is expressed in terms of cybernetic concepts, including self-organizati
on, requisite variety, and social systems as collections of thinking partic
ipants. The results of the analysis show how network behavior affects the c
ommunity and its culture in general, as well as in some specific ways.
