How would the community grow over time?
I would like to see the community only grow at a natural and stable pace that if correctly managed will have savings for hard times, provide for the members and prepare a fund for a future community .The rather elegant system of biology and mitosis would seem an appropriate growth methodology (if done at a reasonable rate). when the community reach a certain size it first of all will remain stable gaining enough resources and savings to create a secondary community and training its members up to a sufficient level so when the savings and abilities of the communities reach a predefined level a secondary property is renovated by all available members followed by around half of the original community leaving to populate it.
As per mitosis and cell division each community can start to specialize and work on a specific expertise, science etc. and be a place where members can go to gain mastery in a discipline, the public can go to be educated or where organizations go to get technical support and help on a particular subject. One should always be careful of over specializing, over specialization breeds in weakness, it’s slow death.
