eldavojohn writes "Two months ago, Tim Berners-Lee unveiled a UK Government data project with the goal to make government data more useful for everyone. Today he is calling on the rest of the world's governments to become more transparent with their nonsensitive data. After only a few months, his project boasts around forty applications for using government data (screenshot example here). The BBC article notes the interesting uses of public data in India and Brazil that are disappointingly lacking in other countries — even the United States. Hopefully the US's data.gov will evolve to hosting apps instead of just data."
