Google Maps has integrated Wikipedia data. It’s a handy addition. In the normal map view, click the “more” button at the top of the map. It offers two selections: Wikipedia and Photos. Photos are nice, but the Wikipedia elements are great. Click Wikipedia and the map populates with several W’s. Click on a W and see a location-based Wikipedia entry. Try the interactive map of Manhattan, below (you can also try out the photos from here). Very handy when you are looking for something to do in a new city or vacation spot.
