This is complete off topic, but...
We all take great care about our small but constantly growing online
world Commons. However, physical world still need care too. I invite
you to join a Google cause: http://maps.google.com/help/maps/cleanup/
Not because of Google PR, but because of great idea.
I think to clean up a place where I took all my dragonflies images -
there are many broken glass battles around.
With best regards,
