This is a presentation on Social Networking done by me in November 2007 during a mentoring programme conducted by our university- University of Moratuwa, Sri Lanka. Now the things have changed, some details are no longer valid. However, in this presentation I mentioned about isolation of social networks (i.e. no interconnections among multiple social networks), and it still remains and no one has yet been able to address this in an effective manner. This is one of the major points I wanted to convey during my presentation.
