New on Google Earth: Panoramio and Wikipedia

In the morning, I was looking for a shorter path for my travels, and I sow these little white circles with an blue x on them on the map, and some gray ones. (You should see them too if you see a right part of the map - peek a city that may contain something interesting - and if in the layers panel the Geographic Web is checked).
So the x-circles are from Panoramio and the grey ones are from Wikipedia. (they are like the sites favicons - those that appears in the address bar before the site url).
Let's what the gray icons can do:
It retrieve informations from Wikipedia and show it in Google Earth, I found it nice.
The Panoramio little circles are nice too, you can see a picture of that place the circle is.
But the bes way to see it is in Google Earth. Find some time to watch it.
