Social gets personal as new network limits friends

Path arrived at the idea of limiting users to a network of 50 people following research done by Oxford University Professor of Evolutionary Psychology Robin Dunbar. He espoused that 150 is the maximum number of social relationships that the human brain can sustain at a given time and that 50 is roughly the outer boundary of our personal networks. Facebook's approach and that of other social networks from Bebo to MySpace and Google Buzz is at odds with that thinking.
