Eric Fischer (who describes himself as “Geek of maps, failed transportation plans of the past, history of technology, computers, pedestrianism, and misspelled street signs”) had a bright idea: he mashed up data from Flickr (the orange dots are pictures uploaded to Flickr) and Twitter (the blue dots are Tweets) to reveal that people Tweet more in urbanised environments and upload photos more in scenic surrounds. The white dots? Locations that have been both Tweeted and uploaded to Flickr. Makes sense, huh. Yup, the obvious has never been displayed so beautifully.
