Check out Arronland’s NY Times Widgets. This site capitalizes on the fact that the New York Times publishes a lot of useful descriptive metadata along with each of its stories.
Metadata is data about data in this case, descriptors about each story such as the nation involved, section in which it was published, and much more.
Programmer Aaron Straup Cope scrapes this descriptive metadata daily and repackages it in intriguing ways. For example, he builds automatic maps based on the locations of today’s stories. (Not clickable, but still cool.) Metadata rocks.
