My Maps/My Places isn't placed prominently in the new version of the desktop maps, but if you click the gear in the top right corner it is shown, but as they haven't built in the new platform yet it takes you back to classic maps. I can see how you might be worried they'll kill it off and so don't want to waste development cycles on it, but what about Google Maps Engine? It was recently released and you can import maps from My Maps into it. See my map here: https://mapsengine.google.com/map/edit? ... Cdi2VLG7WY
