Small-scale society
From Cyborg Anthropology
"Generally a society of a few dozen to several thousand people who live by foraging wild foods, herding domesticated animals, or non-intensive horticulture on the band or village level. Such societies lack cities as well as complex economies and governments. Kinship relationships are usually highly important in comparison to large-scale societies". http://anthro.palomar.edu/tutorials/cglossary.htm
(livejournal groups are an example of small scale societies)
