This article shows the world usage of Flickr and Twitter.
"Sometimes it’s very easy to forget just how quickly the world changes, particularly with the all-conquering innovations that develop on the internet.
After all, it’s just five years ago that Twitter first opened its doors to an unassuming public, and nobody could have begun to imagine the impact that the network would make around the globe – culture to culture, person to person – in such a short space of time.
These incredible maps, created by Eric Fischer, use geolocation to show how both Twitter and photo-sharing service Flickr are spreading across the planet.
The locations of tweets are detailed in blue, while those from Flickr are in red/orange. White dots show locations that have been posted to both."
