As well as hashtag communities, where membership is implicitly determined by virtue of using a particualr hashtag, it also struck me that curated lists might also represent a view over a community as identified explicitly by whoever is curating the list. So for example, if we take the Guardian’s list of Twittering MPs, we can grab their friends lists and look to see which other MPs each MP is following….
The simplest visualisations are simply over the friends graph. So to start with, how about a view where node size represents the number of MPs following an individual, and heat/colour represents the number of MPs followed:
The converse view uses node size to represent the number of MPs an individual is following, and heat/colour to depict the number of MPs an individual is following:
More later [here, in fact: More Observations on the Twittering MPs’ Network…], maybe including a look at what “clusters” appear. Are MPs following folk in their party, or elsewhere…?;-)
