Googlemapsmania has noticed that Google maps now includes Wikipedia articles relevant to the locations you are viewing.

"In what is proving to be another busy day for Google, Wikipedia articles have been added to Google Maps. The new Wikipedia tags can be turned on via a 'More' button that has been added to the top right hand corner of the map.

When the Wikipedia tick box is selected small 'W' tags appear on the map where Wikipedia articles are available. Clicking on the 'W' tag will open an information window containing the Wikipedia article.

Panoramio photos can also be turned on via the same 'More' button. The photos option however feels a little superfluous considering Panoramio photos were added last week and can also be turned on in the left-hand panel. Intriguingly the photos turned on by the 'More' button contain a Panoramio logo whilst the ones accessed by the left-hand side panel don't, even though both sets of photos are served by Panoramio."
