A fascinating set of highlights over a recent report ‘Mapping the global Twitter heartbeat: The geography of Twitter’. Perhaps the brave new world of online media isn’t quite as fair and international as we might like to think.
Other than that revealed in the tweet that lured me in, there’s a bunch of very interesting info on how to get proper geographical data from Twitter. Where people tweet from, apparently, has little influence on, well, their online influence (square brackets my own):
Kalet et al. [the authors] also carried out a comprehensive analysis of geo-tagged retweets. They find that “geography plays little role in the location of influential users, with the volume of retweets instead simply being a factor of the total population of tweets originating from that city.” They also calculated that the average geographical distance between two Twitter users “connected” by retweets (RTs) and who geotag their tweets is about 750 miles or 1,200 kilometers. When a Twitter user references another (@), the average geographical distance between the two is 744 miles. This means that RTs and @’s cannot be used for geo-referencing Twitter data, even when coupling this information with time zone data.
