Do a little searching: lots of tutorials on the Maps API, with pre-reqs of Javascript and OO... give me a break! Yes I'm a programmer, no I don't know those nor have time to learn them just to inset a couple of maps in my blog.

Google's My Maps allows you to save a complex route with custom icons, but not via anything but road, public transit or airline, nor any other type of overlay. Bing, Mapquest have similar constraints. travellerspoint and others let you make itinerary maps but just draw straight lines from point to point.

There must be many who use google maps and who would like to show a detailed, customized route over water (think of all the weekend sailors!) or by private plane (private pilots!) or cross-country by hiking or skiing -- decorated with maybe a few circles, arrows, labels -- maybe links to pics taken at a given site.

So here's the idea: a user-friendly "draw on your map" website. It lets registered users put scalable point-to-point routes and other decorations on maps via a normal drawing-tools interface (virtual "pen", "hiliter", or "stamp"), compiling to maps API javascript under the covers. Host the decorated map and provide shortcut view and embed links. Paid mode unlocks more stuff (graphic features, number of waypoints, number of maps).
