Social Network Analysis with the "Clique Finder"

One of the things I like about LiveJournal is that it makes a certain amount of social network data available and visible. Yes, the whole "friends list" concept is overloaded by being a reading list and/or an access-control list depending on the user, and different people have wildly different criteria for adding someone to the list, but it's still a lot of data, and fun to play with.

One of the fun tools people have developed to use this data is the Clique Finder, which finds the largest group (or groups) of users who have all other members of the group listed as friends containing a particular user. At the moment, I am a member of 7 cliques of size 9, but there are interesting overlaps between the seven.
