Two Hemispheres, Green, Weblike, and one heck of a long spreadsheet.
Tim Berners-Lee not too long ago made a TED conference speech about the future of the World Wide Web. He claimed that the future is not in the flashy games and movies etc., but in databases.
He gave a few wonderful examples of how sharing databases around the world connects information and leads us to greater understanding of all things on a global scale. The explosion of databases available online since that speech has been rather noticeable, even when simply browsing nonchalantly on the web.
