I just got a MindMap, which details some of the social relationships among users of LiveJournal in a visual format. If I understand it correctly, it is generated by using various formulae from set theory (and maybe group theory too) . . .

There's more about it at this link -- more info about the meaning of the sizes, shades and placement is here. This clickable graphic seems to be a more elaborate way of showing who is friends with whom, and showing circles of friends -- much more so than the clique meme I used in this prior post.

I have re-generated that meme, since there have been changes to my friends list since then:

I am a member of 3 cliques of size 4


  • blaisepascal, skitten, mowglikat, theentwife

  • skitten, mowglikat, craig139, theentwife

  • skitten, glowroper, mowglikat, theentwife



  • Find the largest clique containing:

    Something that I find interesting in my MindMap has to do with the placement of the various LJ user IDs. There seems to be a bit of a pattern in that IDs that are related in some real-world way seem to be close together. Relatives are close, people from the same part of the world are close, those who are lovers or live together are close, those who play the same online games are close, user IDs for the same person are close -- I'm curious as to how that occurred . . .

    Is it just happenstance? Or is there something in the formulae used to generate the MindMap that is able to tease out these social relationships? The reason I wonder is that for many of these IDs the Friends lists are small -- sometimes just one or two or three other user IDs. I find it fascinating that these relationships could possibly be extrapolated from such apparently flimsy data.

    Are there supposed to be links between the various names? Because, all I see is a black background with a bunch of names on it.

    I got the free B&W MindMap. The color one (which one must pay for) has lines between the various names, from the ones I've seen. Bu, Mowgli & FeLisa's MindMaps are also all B&W and none of them have lines connecting the user IDs either.

    BTW, in looking at their MindMaps, the grouping pattern that I noticed in mine seems to also be true in theirs, so far as I can tell -- I know who SOME of their MindMaps' user IDs belong to, albeit not all.

    Intriguing . . .

    From the next-to-last paragraph of my post:
