Studying a language works best for me when I have a serious project to develop. After surfing around I came up with the idea to extract the travel map I developed for journizer.com to a Autobahn81 product for sale.
The new version of the google api is not compatible with the old one. So the new travel map item was developed nearly from scratch. The guys at google did a really great job improving the api. On of the best things on Gmaps api V3 is, that you don’t need an api key anymore.
