    1. There are many other questions. Of course existing systems on the earth may be very much influenced by the geographical reality of a two-dimensional surface. Historical groups have been nested geographically. So though there may be aspects in which community size is scale-free, that maybe a completely different optimisation problem from the one we have when on the Internet anyone can connect to anyone. If you could devise an algorithm for connecting people into groups, and so that they each participated in communities of different sizes in a scale-free way, then how much more effective (at solving problems, etc) can you make a web-based society which ignores geographical borders? To what extent does humanity as currently connected by the web in fact deviate from geographical nesting anyway?
