This is the NodeXL map of connections among people who tweeted the hashtag used for the conference “#sunbelt”.
Having now seen several of these maps for other topics and events (see: http://www.flickr.com/photos/marc_smith/sets/72157622437066929/) this map can be placed in context. It is a small group, but has a high density of connections. It lacks isolates, the people who say the term but do not connect to others who say that term. This means that this is a very “in-group” population: if you know to use the #sunbelt hashtag, you probably connect to someone else who uses the term. It is a single major cluster of connected people, no obvious sub-graphs or clusters are visible. Not everyone is central in the graph, and those who are have a prominent role in the network science community. Here is the top ten list of #sunbelt mentioning twitter users ranked by betweeness centrality.
