Social Media cartographer Eric Fischer has created this map illustrating physical movement and the movement of tweets: green denotes physical movement; purple is @replies from someone in one location to someone in another; white is a combination of the two. One surprising feature of Fischer’s map is the traffic in and out of Indonesia. According to a 2010 study, about 21 percent of Indonesians are on Twitter, making them the most Twitter-addicted nation. Possible reasons for this might include their large population (nearly 240 million), cheap access to mobile devices and English as a commonly spoken language. Fischer has also created maps highlighting content on Flickr and Twitter, that we wrote about on PSFK, and he also created the maps (below) that illustrate the specific movement of tweets across the United States.
