I am seeking a missional use of the socialmedia. These two interesting books offers some interesting insights.
Jessie Rice (2009) correctly pointed out the that phenomenal growth of the social media is the human need for connectivity- whether virtual or real face-to-face. Much of the book explains what facebook is all about. However, Rice does not offer much when it come to a discussion a virtual community. He does not answer the question whether such a community may be formed and if so, in what form? Rice however offers some guidelines on using facebook.
Christakis and Fowler (2011), two well known and respected social scientists examine the importance of human connecting in the second book. Though at time quite technical, they show the importance of connectivity for human well-being. Check out the book website
