thought provoking discussion of group size in social settings

Chris Allen, over at Life with Alacrity has posted a thought provoking discussion of group size. The post takes the Dunbar Number (i.e. the upper bounds on human groups is about 150) as it’s starting point and considers the affect of the purpose of the group (ie survival vs other activities) on the optimal size. Along the way, he provides some interesting references to empirical data from the on-line multi-user gaming. Check it out.
