I remember this phrase as being used in some of the “Church Growth” books,  encouraging Churches to use some “marketing” techniques and recognize that organizations grow when they avoid too much “diversity”.  In Chapter 7, Nurturing Virtue In Community,  Schultze identifies this as a tendency of cyberspace:

We can talk about cyberspace as a global village, as if it unifies the world into a community,  but our actual use of cyber-technology suggest that we select our online affiliations to maximize our own narrow interests,  not to reach out beyond those interests. (p.173)

Schultze suggests that Cyberspace encourages this,  which it certainly can, but this is NOT a condition of cyberspace.  It is a condition of natural “flocking”,  as unhealthy and “provincial” as that may be.  As questionable as the Church Growth statement strikes me as an intentional strategy,  I also recognize that it is the practice of most Churches,  since people tend to gather with “like-minded” folks.  The responsibility to nurture diversity is as much a challenge online as it is in “traditional” gatherings.
