Social media networks have meaningful and somewhat stable macro-structural topologies, which constitute a kind of terrain subject to mapping and dimensional analysis. Therefore one might view “sociocultural terrain” as organized in two intersecting planes: geographic and cyber-social. Throughout most of history, the geographical plane was where people associated, organized, traded, and struggled. In the 21st Century, the cyber-social plane is rapidly becoming equally if not more important as the dynamic locus of human relationships.
