A Gephi Visualization of Gephi on Twitter

This is a visualization of Twitter accounts that follow and are followed by @gephi that I made using ... Gephi. I collected the data using NodeXL. Two accounts are linked in the network if one follows the other on Twitter. Nodes are sized according to their degree. The modularity clustering algorithm finds 8 different groups among the accounts.  The blue group in the upper left, where I live, contains most of the network science crowd: @duncanjwatts, @ladadimc, @barabasi, @davidlazer, etc... The green group in the lower right seem to be data/visualization folks. I filtered out all of the nodes with degree less than four, before which there is a large contingent of accounts that followed @gephi, but with no other connections in the network.
