Japan Earthquake: Locating the tweets (Part 4)

“Location” has become an essential component to many social media technologies.  Not only is it important to convey “what happened?”, but also to reveal “where” it happened.  Check-in technologies have become popularized by companies like Foursquare, Gowalla and Yelp, further blurring the lines between the content and the geo-coordinates.  Twitter has traditionally not put an emphasis on the notion of “place”, but they did announce, in late 2009, their own geolocation feature.  Users were now able to enable geolocation in their settings page to reveal the exact location of where they are tweeting from.  While twitter itself does not have an interface for mapping tweet locations, making the data available through their Geotagging API allows third party applications access to this information and map them accordingly.
