Here is a nice way to display high resolution network maps: zoom.it!
This is a map of the connections among the people who tweeted the terms “FOCAS11” or “Aspen Institute” on August 2, 2011.
Connections among the Twitter users who recently tweeted the word Aspeninstitute OR FOCAS11 when queried on August 2, 2011, scaled by numbers of followers (with outliers thresholded). Connections created when users reply, mention or follow one another.
Layout using the “Group Layout” composed of tiled bounded regions. Clusters calculated by the Clauset-Newman-Moore algorithm are also encoded by color.
