Languages divide and unite. Eric Fischer majored in linguistics in college before becoming known for making maps, and he combined the two to make this map of Twitter activity around the world. Shown are geotagged tweets from May 14 to October 20, 2011, recorded using the Twitter streaming API. Each dot is a tweet. If there are many tweets at the same location, they diffuse outward but fade with distance. Dots are color-coded by language using Chrome's open-source language detector. English tweets are gray; other colors are optimized for maximum distinguishability. Labels on the right name those languages that have more than 10,000 tweets. No national boundaries are shown, yet a map of Europe emerges. The Netherlands has the highest density of tweets. In some areas, Twitter usage seems to follow the spines of the transportation networks—see central Spain and along the Trans-Siberian Railway in Russia. Overall, the map gives an indication as to the level of our social-networking obsession—some parts of the world are highly active while others are lost in the dark.
