Decentralization: The next Generation of Online Social Networks

Is there anybody out there reading this blog??? The following paragraph is the current draft for my BA-Thesis abstract. I’ll be glad about your unvarnished comments!

Abstract
Online social networking is becoming more and more popular these days. Social networks like Facebook, Linkedin and Myspace have millions of users everyday. Facebook surpassed Google in the US to become the most visited website. Social networks compete for attention, users and market share. One of their appliances to reach these goals is to keep all available information under control and at one place, they form so called information silos. This determines several problems regarding availableness and privacy. Actually the mentioned online social networks also try to collect information from other Web 2.0 services like Twitter or flickr and strive for presence in nearly every social media system. The users are motivated to centralize their Web 2.0 activities at a particular information silo.
The fact that people want to keep control over their data, be in contact with each other and share their experiences across technical borders, makes it necessary to rethink the concept a centralized social networking architecture. By adopting a decentralized approach, the diversity of real world sociality becomes manifest on the web. User won’t be bounded by a particular provider but will be able to create their personal social networking service.
The purpose of this paper is to sketch an open and comprehensive architecture for social networking built upon technologies like Semantic Web, Linked Data and decentralized authentication mechanisms.
