Mapping Twitter Chats

This is a network map of the almost 1000 tweets during the #ideachat 1 hour session in November 2010. Individual participants in the chat are shown as purple nodes and the "whole group" is shown as the large green circular node.

People who tweeted to each other [@ messages or RTs], at least twice in the 1 hour session, will have arrows drawn from the tweeter node to the subject node. @blogbrevity <--> @cocreatr indicates that they both sent 2 or more tweets to each other during the session. [We do...
