Metcalfe's Law describes the value of a shared resource (a network) when used by an increasing number of people. The Ringelmann Effect descibes the productivity of an individual when part of a team. According to these two theories, a shared resource becomes more useful when used by more people (e.g. the internet). People become less individually productive when part of a large team (e.g. a large corporate working group).
