Google Maps started to integrate some of the most popular mapplets and user-generated maps. When you search for a location (like Rome), you'll be able to see Panoramio photos, YouTube videos, places of interest, popular searches and maps so you can get a better sense of what to expect if you go there. As you zoom the map, the sidebar is updated to reflect your new location.
The feature is reminiscent of Flickr Places, but the map plays the role of placeholder for geotagged content.
