So I belong to 1000-somthing participants of #PLENK2010, which is a MOOC (massive open online course) run by Stephen Downes, George Siemens, Dave Cormier & Rita Kop. For more information view the course home page .
One of the participants, Tony Hirst, used the Gephi modularity statistic to cluster his Twitter network depending on the strengths of connections between members of that network. The Gephi modularity tool identified a number of different clusters. I found my Twitter ID, mediendidaktik, in the third cluster. It’s really interesting to see that the people I am connected with in #PLENK2010 are mostly (or all?) German speaking. Also I seem to be having 9 connections, some of which I was not aware of, like Uni_Moodle or twoflower29.
Also compared to other clusters, “our” German cluster is not as densly populated as cluster 1 (Canada) or 2 (UK). So again, are our connections in Twitter primarily based on the country we are based in?
