GoogleMaps is an interesting phenomena, Google supplied brief documentation on the API, nevertheless lots of people, not just geeks, started to work on it and step by step the API grows. I guess that that is what web 2.0 is all about. Starting with some sort of Beta and let the community work on it to the next Beta. Frankly I enjoyed my hours with the API documentation and places like Mapki, a wiki on GoogleMaps. The result is a map based search entry for documents.
