Not to be outdone by the CraigsList/Google Maps hack, ListSomething.com has added similar map-plotting functionality to its real estate listings. The service appears to only be in use throughout South Florida. The ListSomething.com blog says;
The ability to view the location of the listing, as well as the surrounding area, will help you quickly determine if the listing is worth pursuing or not. Click on the Satellite link at the top right of the page to have the map display actual Satellite images from space (we highly recommended trying this!).
ListSomething.com credits Mygmaps.com as the large help behind the enhancement.
