List Intelligence: Mapping Lists My Twitter Friends Are On

A tease (and reminder to myself) of something I was messing around with for a few minutes today: a List Intelligence routine that grabs all the lists the people I follow on Twitter are on and that then plots the digraph connecting my Twitter friends with those lists. Using a force directed layout of a sort, sizing nodes (non-linearly) by degree, and then filtering out friends to leave lists, this is the sort of thing I came up with:

My twitter friends in list space

What this approach does (sort of) is identify groups of people I follow that other people have grouped/curated onto particular lists. I suppose the next thing I need to do is compare the list based clusters with social relations clusters (i.e. the extent to which folk follow each other) to see if they turn up similar clusters…?
