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% 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.
