No idea, beyond the ability to hover your mouse over each of the names and find out where they're located geographically according to thei ruser info. On the other hand, the positions on the map don't appear to correspond to locations...
Possibly interconnectedness of the various people. I notice that on mine, all my rpg_aman gamemates, all of whom have each other friended, are clustered together and in the same biggish font size.
I think it's supposed to somehow illustrate what level of influence someone probably has on the sorts of things that you think about/are aware of... with names that are a) larger, and b) closer to you being more signifigant. I think it's based somehow on friends in common and possibly comments made back and forth, but I'm honestly not sure. However, that's what I remember of what it said. I think you should also be able to click on people's names and get to either their livejournal or their mindmap.
