Here is the network graph of all Twitter users that tweeted #ECSCW when queried on the evening of 28th Sep. 2011 (a few hours after the end of the conference). The collection includes all tweets since one week before the query date (i.e. before the start of the conference). Connections are created when users reply, mention or follow one another, and vertices are scaled by the number of Twitter followers. The color of the border of the vertices reflects betweenness centrality. Visualization and analysis was done with NodeXL. Click on the image for a higher resolution version.
