Incredibly smart stuff from Paul Adams.
my two cents
A Google presentation focused on how people network, and a lot of premises explored, like groups, Dunbar Number, social scale, weak ties, strong ties, networked identity.
I disagree with some of the conclusions, based on different starting points in my thinking, and also because I don’t believe most people’s social networks are as discrete as suggested in the examples used. Perhaps I will get a chance to unthread that argument, soon.
However, you can see why Facebook launched Groups before Google has launched their GoogleMe app.
