'My Maps' in Google Maps

Google added KML support to Google Maps allowing users to create their own maps using the web-based virtual map (just like Google Earth). You could pin-point a specific location (you room), draw a line (your daily jogging route), shaded an area (your campus). You could then add plain or rich text description (which allows images and outbound links). Finally, you can publicize your map and allow others to search them. By building up a community in Google Maps, it adds in more lively information making it more useful to users (and spending more time). One thing that I couldn't find (tell me if I missed it) is a public URL for my maps. The sense of community could be enhanced by allowing users to set up a profile like Google Coops.
