I have a hard-to-test-theory involving the nodes with high betweenness-centrality that may explain regional popularity. The "most-connected" (eigenvector or page-rank) nodes may be much less valuable than the "more-diversely-connected" nodes (betweenness centrality being a good measure of this)) in their ability to persuade conversion.
