Great Richard :)

We in enkel are looking to restructure a bit along the lines of crews and congregations. We’re not sure about the number of people we should strive for in each though. Dave Snowden (of Cynefin fame) wrote about this:

“Social process and experience over time constitute a modification of the interactions so that the individuals have less significance. Dunbars number, relates to grooming and the number of acquaints we can maintain, it appears to be a neo-cortext limit and in more recent writing Dunbar has suggested that the cortex is the size it is as 150 is the optimal size for a hunter-gatherer community. The Bernard–Killworth suggestion which roughly doubles this is based on field studies in a modern society where city states, remote education and identity structures change the field a little, a subject to which we will return in a future post. Other studies show a number between 15 and 30 as a natural level of trust and we have Millers number on short term memory.”
