It takes the stories from an RSS news feed, then checks the words in each story title against a list of countries and cities on the Earth. Any matches will result in placemark being placed on GoogleEarth, along with the news item title. You can then click on the placemark to read the summary, then then click through to the original story.
I like it. I think this kind of thing will become standard on news sites in the future as news organisations realise the day of the simple headline and story is dead.
