The connections between nodes is computed using betweenness centrality, a measure of a person's importance in a social network. This measure gives more weight to friends that branch other cliques. I'm not sure what the size of the nodes relate to.
The colors of the nodes indicate cliques/clusters - cliques have many friends within a group of friends but few connections to others outside the group.
- The purple group are mostly friends who were in the social club Knights with me in college.
- The red group are mainly active Harding students, employees, or spouses. Becky is in this group.
- The green group are people I know from when I lived in Denver years ago. My sister Sara is in this group.
- The blue group are other friends from college.
When I boil it down to only 4 friends, I'm left with Becky (78 friends in common), Hank Bingham (48), Jim Miller (45), and Mark Elrod (45). What would be interesting is if these connections could be recomputed based on communication levels... which friends do I communicate with the most?
