I blogged a couple weeks ago about how Google Maps announced support of KML (location information file for Google Earth), and that the KML files that Where's Tim generates where not loading correctly.
Well, sometime between now and then Google fixed the bug and now you can see my current location that was meant to be viewed in Google Earth on Google Maps!! Ok, it's not that cool for Where's Tim since it already lives in Google Maps, but it has potential for other applications.
The query string in the Google Maps url accepts urls that contain a query string themselves. So you can take Sami Sattanen's current position KML that looks like this:
And it works as expected.
