Alternate to Google Earth

Recently i came through this website http://www.wikimapia.org/ . The beauty of this is you need not download software and install on your system liek the google earth ,we can just view in the browser itself and the prominent places are marked with information tags .These really help us to locate a place very easily .But the drawback is we can't rotate or tilt as in google earth.
On the whole it is very nice
