A professor at a US university has created a map of the world entirely made up of tweets.
Alan Mislove plotted geo-tag information from 275m tweets gathered between January 2011 and April 2013.
The result clearly shows those areas of the planet where Twitter is most popular — along with some of the most unlikely.
Alan, who is based at Northeastern University in Boston, Massachusetts, used only geo-tag locations to create the map. All the roads, coastlines and other features evident on the map are present due to people using Twitter at those locations.
Here are seven of the more intriguing features of Alan’s map, which become clear when you zoom in for a closer look.
