When we think about communities we need an effective model of what they are and how they operate.

What then is an effective model for a community? In "Twitter And Teargas", Zeynep Tufecki argued that the community afforded by Twitter was unable to effect long term, substantial change and therefore Arab Spring is now a footnote. Twitter affords flash mobs.

That concept - affordance - provides a hint for a model of communities. The obvious question to a hacker is "what kind of social system would afford long term substantial change?".

Another insight is that the afforded mechanisms determine the community. This is really a restatement of the Sapir-Whorf hyptothesis. From "your language determines what you can think" to "your social mechanisms determine your community". Roughly.

Another insight (corollary?) for Sapir-Whorf is that your language prevents you from thinking some things. So one could try to understand what "following" as a social mechanism prevents prevents?

Out of this kind of analysis emerges a different take on communities all together. For the hacker in us, John Holland's "Hidden Order" provides a generalized model that can be used to at least create a pseudo model for creating a simulation of the community mechanism.

Although John Holland talks about Complex Adaptive Systems, I personally find "Gestalt" a less cumbersome and effective term. A gestalt is something greater than the sum of it's parts and that can only be true(ish) when the parts interact. So entities + rules + message bus => Gestalt. For ants this is {ants + ant behavior + pheromone trails } => ant colonies. One could conjecture that for humans this could be {people + behavior + money } => economies. Or more cynically => corporations.

The complexity and emergent behavior of the {rules + message/bus part} part is probably best revealed by Wolfram's "A New Kind of Science".

This is an incredibly important talking for our time. What is the most effective way to get rid of ants? To destroy their ability to use a pheromone trail. Perhaps we could just put advertising in it?

Communities are not fungible
