open source communities have three main traits
Community lessons from architecture and urban planning
Dave Neary manages open source standards at Red Hat, so he thinks a lot about what makes open source communities work and what makes them unique.

A Pattern of Language examines the intimacy gradient, which is moving people from the most public space to the most intimate, in that order only. This can be applied to how we communicate with people too, i.e. from forum to moderated mailing list to private email.
The Death and Life of Great American Cities details how successful neighborhoods and centers have primary, secondary and mixed uses. By using all three, people are made to feel safe and highly productive. For example, having employees in a variety of geographic locations, working at variuous times, and having employees who work fulltime and parttime hours.
