Abstract: Relationships in an e-society The dynamics of social groups as they interact electronically is central to how modern society operates. A study of patterns of information exchange between two groups of individuals — collaborating scientists and cell phone users — has been used to devise an algorithm that relates information exchange to group stability. The data show that small groups have a few strong relationships at their core. And as long as these persist, the clique remains. But for large communities, continuous change is the key to stability. These findings offer a new view on the fundamental differences between the dynamics of small groups and large institutions.
