This map depicts the physical movement of and movements of tweets. Created by Social Media cartographer Eric Fischer, this tracks the physical movement (in green) and @ replies from someone in one location to someone in another (in purple) and a combination of the two (in white).
Fischer has also created maps on the use of Flickr and Twitter, including a map that illustrates the movement of tweets in the United States, a zoom of a subsection of the world map above.
The biggest surprise on the above map is the high level of social media movement in and out of Indonesia. According to a 2010 study, Indonesians are the most Twitter addicted country, with about twenty one percent of the population on Twitter. This could be attributed to the fact that there is a large population of almost 240 million with access to cheap mobile phones and a prevalence of spoken English.
The map about reports trips with the exception of Null Island, with all other geotags trusted. The endpoints of the trips are based on data but routes between is fabricated and the brightness of the lines are logarithmic. The data is taken from the Twitter streaming API through September 1, 2011.
