Abstract
The spectacular recent rise of Social Network Sites (SNS) is rooted in their capacity to provide social integration under highly complex conditions of contemporary culture, society and individual life: by allowing individuals to communicate comprehensive and reliable information about all their cultural preferences as well as their social adherences and identifications. However, they also contribute to a downgrading of social life by obliterating more subtle nuances between different types and qualities of human relationships, by reducing personal autonomy in self presentation and impression management, and by inserting individuals into settings of increased supervision and social control.
