This map widget is terrible. There is no information about each dot on the map screen, you have to click it and go to a new page (with a load spinner!) to see what it is. When you go back to the map, it resets to the original location and zoom level instead of where you had it when you clicked. You also can't zoom the map very far.
A map is useless if you can't quickly view and compare multiple locations. Basic information should be available on the map screen itself, ideally with different icons and/or colors, instant popup dialogs, etc. If you want to have additional detail on a separate page, that's fine, but you shouldn't have to leave the map to accomplish the main function of the site.
