It is critical that point and polygon features display labels, both in the ArcGIS Explorer Online version
This idea has been merged with Labelling in ArcGIS online.
and in the ArcGIS.com version. The embedded maps in either case revert to the ArcGIS.com version
and we must have labels that draw when the map opens.
Also, if symbols could be drawn to represent current environmental conditions -- to keep our maps "live"--
the maps would be much more useful.
