Interactive maps are a way combine stories, photos and videos to tell better stories online.
These maps, sometimes called mashups, allow readers to see where the story is in relation to their world.
Here is an awesome mashup from Freep. It uses stories, photos and video to capture a portrait of Detroit. Be sure to click on the stories tab and read about how they made "a 4-month, 2,700-mile odyssey through Detroit's 2,100 or so streets."
Not all mashups are this complex. Some are just useful or fun tools that allow you to find WiFi hotspots, drive like a madman or find high-risk areas for pirates.
