Newsmap

There are many mashups that combine news and maps - some map the news, and others locate the news on a map.  A particularly impressive and handsome example of the former is Newsmap.

Another example, and one that appeals to the morbid interest New Yorkers have in the misfortunes of others is Gothamist Maps, "the best way to see what's going on where right now."  The "what"  includes "overturned auto", "tripple stabbing", "person under train," "fatal all hands" (fire), and other ticklers of the imagination.  (actually, to be charitable, although the map only covers NYC, this kind of service would probably find an audience in other cities/nations as well...)
