OpenStreetMap Points of Interest in Google Earth
If you want to display Points of Interest from OpenStreetMap in Google Earth, this KML is maybe the right thing for you. At the moment it displays OpenStreetMap nodes and ways tagged with historic, leisure tourism, shop and amenity. Unfortunately lots of nodes aren't tagged like it's recommended on http://wiki.openstreetmap.org/wiki/Map_Features and they don't get a own icon in this layer.
Check out Google Earth, OpenStreetMap and CloudMade for more information.

You can also create a customized network link as it is shown below. If you set the threshold to a big number (the visible distance on screen in km) the loading will the take a while.
