Google has added a new feature to Google Maps called "My Maps" that lets you create and share personalized, annotated maps of places that are important to you. Add descriptive text, including rich text and HTML, embed photos and videos in your map, share your maps with others, and open it in Google Earth. Additionally you can apply mash ups to your map such as Google Real Estate Search, Our Earth as Art, and others including my personal favourite, Crop Circles.
