The live map
DOES use the location entered by the RB owner in Preferences - Home Station Data. But, and its a big but, only if Google Earth can handle all the lookup requests. Many of the lookups will time-out, resulting in BLUE pins.
If you want to see the list of all user locations, just right click on the page, and View Source. You'll see all the locations listed as geoStuff statements.
