Quick, what is the fifth most photographed building in New York City? Studying geotagged data from 35 million photographs uploaded to Flickr, computer scientists at Cornell have discovered that the building is (virtual drumroll...) the Apple Store on Fifth Avenue! They also learned that while New York is the most photographed city in the world, London hosts four of the most photographed landmarks. Check out the New Scientist for the names of those landmarks as well as the scientists' account of how Flickr statistical analysis can provide insight into "what the world is paying attention to."

No doubt, most Daily Travelers have already encountered mapped versions of the spread of the A (H1N1) swine flu. Here's a version on Google Maps. MSNBC.com takes the state-by-state approach. For the money, however, BBC.com hosts the most interactive swine flu map, thanks to a slider that allows users to track its spread over time. We hope not to see many more updates.
