A few hours ago, I was notified of the release of the new MapQuest toolbar for Firefox, with skyhook-based geolocation inside. I wanted to try that beast. Please compare the two following screenshots. The first one is MapQuest in action, the second one is my own app...

And they're both based on Skyhook... Well done Mapquest ! Oh I forgot it belongs to AOL :-/

Nota bene: my very first mozilla extension was a mapquest sidebar for netscape 6... I called MapQuest to let them know, they rejected it.
