Google just released a very cool update to their already useful Google Maps service. Google MyMaps allows users to easily create customizable maps by using an intuitive web-based user interface to place points on the map, and draw lines and areas.  Any of the points can then be labeled with customizable text that may include photos and video clips. I’ve always been impressed with Google Maps, and this is a nice addition that makes more useful in a much different way.
One of the interesting things about Google Maps is that they have always offered an API for others to extend the functionality.  I don’t think that the MyMaps feature adds much that couldn’t have been created by somebody else by using their existing APIs.
