The Google Earth team announced today on the official Lat Long blog a new feature that makes it easy to share attractive screenshots depicting Google Earth explorations with Google+ circles. Run the recently released Google Earth 6.2 program, find a place you like, zoom in on the best possible scene and hit the “Share” button. This sends a snapshot of the 3D view to your Google+ stream. Note that you must sign into your Google Account in the Google Earth application to share screenshots with Google+ circles.
Note: Google Earth is on Google+, too!
