There's a cool feature in Google Maps that's probably been around for a while but I haven't noticed it:  Wikipedia links.  On the map itself, near the buttons for switching between map and satellite views is a button that says "More..."  One of the options is Wikipedia, which shows links to Wikipedia articles that have something to do with the map being viewed.  In most areas, it's just information on cities and towns.  But in more zoomed-in areas, there's information about historical events and unusual facts.  Very cool. #technology
