Value of Social networks
“The value of a social network is defined not only by who’s on it, but by who’s excluded,” says Paul Saffo, a Silicon Valley forecaster. Despite their name, therefore, they do not benefit from the network effect. Already, social networks such as “aSmallWorld”, an exclusive site for the rich and famous, are proliferating. Such networks recognise that people want to hobnob with a chosen few, not to be spammed by random friend-requests.
This suggests that the future of social networking will not be one big social graph but instead myriad small communities on the internet to replicate the millions that exist offline. No single company, therefore, can capture the social graph.
