M&G is leading the Twitter Network in SA



Analyzing the Twitter network of 500 South African journalists shows a prominent role for the tweeps of the Mail&Guardian. Using the Twitter names on Hacks List (http://hacks.mediahack.co.za/ ) downloading their relations, and analyzing them in Gephi (www.gephi.org ) and NodeXL (http://nodexl.codeplex.com/ ) creates the following graph:

In order to make this hairball a bit more attractive I have set size to authority and gave different groups a color. (Use the down loadable pdf to zoom in) This network consists of 506 persons, sharing 2503 relations, which gives a density of 9%.


For detailed analysis we have to dig deeper than this graph. Here is the Top20 of tweeps for authority:

The M&G is the medium with the highest number of journalists on Twitter; 20 journalists with nicdawes leading, which is 4% of the 500 in the list.
The journalists of the M&G are not closed elite on Twitter; that is only listening and following each other. Creating groups, tweeps how are closer connected and share more relations in the Twitter network, shows an interesting picture.
In the Twitter network the following 6 groups can be constructed:
Groups in the Twitter network


The biggest and therefore most important are: group 0 (color green and 28% of the the tweeps) dedicated to news and opinion and group 4 (color purple and 33% of the tweeps) dedicated to hard news. How is M&G related to these groups?

Nicdawes of the M&G is leading in group 0, which concerns news and opinion. Vernashi plays a similar role in group 3 where Media24 plays an important role.
The twenty journalists at the M&G are as follows divided over the groups:

It shows an interesting division over different subgroups in the network. 6 M&G journalist are connected to the news and opinion subgroup were freelance journalists are in the majority. 9 of them are connected to the hard news subgroup were other leading media are represented.
Their mutual relations-the M&G network- looks as follows. It shows of course that the M&G tweeps watch each closely, which is not uncommon among journalists, as is shown by an analysis of UK journalists in the Guardian.
