@evan i see where you're coming from but i think that social networks are not the same as any other communication network. there's an element of community and community management that isn't present when you're just communicating or just publishing. w/r/t metcalfe's law, as harsh as it may sound, some people bring *negative* value to the network. some networks have negative value. there are some networks i don't want to be part of, and some people i don't want to be reachable or to be reached by
