Popularity is important, but there are other important roles. Nodes with high betweenness are important in transmitting new information, ideas & opportunities. Some nodes can reach the whole network more quickly than other nodes. How close a node is to all other nodes. Create a matrix of shortest (geodesic) distances between nodes. Average distance between a node and all other nodes. 1/average distance is the closeness centrality of the node.
