Valerie at posterous writes, . . .the density of conversation falls off very fast as the system scales even a little bit. You have to have some way to let users hang onto the less is more pattern, in order to keep associated with one another. (end quote) (How do I turn off italics? I tried ending the quote and of course using the italic toggle.)
In this quote, Valerie assumes community (or "group" in her usage) includes close relationships between members (in my last post I refer to this as "intimate" community). Most others in this class describe community as much more loosely woven. For them, scale is irrelevant and there is little mention of communication among more than a few members. We need to develop a vocabulary that distinguishes between varieties of community because I think all of them fall within the meaning of community in this course.
