Twitter Social Network
People have different intentions when they share information through social networks, says Akshay Java, a member of the eBiquity Research Group at the University of Maryland, Baltimore County. He cites three purposes that bring users to the microblogging site Twitter, where they share brief updates via text message, instant messenger, and the Twitter website: finding information, sharing information, and having conversations. These images show the different networks produced by the different types of communication. When all connections as of April 2007 are mapped (top image below), news sources appear as huge nodes. When maps show only mutual relationships (bottom image below), in which all users both share and receive information, nodes are smaller and the network appears more tightly knit. (The different colors reflect a loose attempt to group close contacts together.)
