A demonstration of NodeXL used to extract a network of related people from twitter who all have tweeted the term "digg". The demo illustrates ways of using network import features, the auto-fill columns feature and the dynamic filters features. The free and open NodeXL project (http://www.codeplex.com/nodexl) and the related Connected Action blog (http://www.connectedaction.net) provide background, support, binaries and source code for NodeXL.
