David Megginson has put together a really nifty little AJAX/Google Maps application to allow people to record what airports they’ve been to, and record comments about those airports. He’s put me to shame, since I’ve been intending to do something with AJAX and Google Maps for over a year now and haven’t even started.
But in spite of my jealousy, you can click the above link and see the 30 airports that I’ve landed at so far. The page doesn’t work 100% correctly in Safari, but it works great in Firefox.
