graphjoin results

Brad asked if I got any interesting results.

When I run it over me + all my LJfriends - all people in that set who only have one link into it (1848 users total), it finds:
two huge groups (not too interesting),
one medium-sized one:

that appears to be primarily LJ support and people from school, and then finally two small groups:
*** 313: lptran puzzlefite limenaide almondsilk rcyang supercat1102 ktnguyen qmdau
*** 328: diapholom hajime kayeyem xian nocte _generica jehilia soulwatcher bbt

The first one is my ex-roommate, his ex-girlfriend, and a bunch of his friends.
The second one includes two people I recognize from a group of friends in Australia. I don't know any of the others.

I think the problem is that by picking me and all of my one-hop friends, the nodes are unevenly distributed around me. There's also a low "q", the value the algorithm tries to maximize to indicate clustering strength. I wonder if throwing more data at it will make it worse or better...?


Anyway, if you'd like to play with it, the code (in C this time!) is up in my arch repository. I even put up simple instructions for checking things out for people who've never used arch.
