ArcGIS Online (not Explorer Online!)

ArcGIS Online might be my answer.  Although there are still data import limitations, performance is faster. The interactivity for the public user is excellent.  I am still working on this map of energy resources in East Asia, but here is the link and a sneak peek:

ArcGIS Explorer Online: Limitations

Recently, I have become invested in figuring out the best ways to share GIS maps with the public, those who don't have GIS software.  I want the public user to be able to interact with the map (zoom in and out, scroll, click features and read attributes, etc.).

Options:
ArcGIS Online
ArcGIS Explorer Online
Google Earth (Pro)
OpenStreetMap.org
PDF with layers that can be turned on and off (Was recently told this was an option...)
SVG file that allows for great rescalability (able to be re-scaled)

So here is one experimentation with ArcGIS Explorer Online:

My shapefile for province boundaries was barely accepted (too large!), so I just imported provinces with the highest population density. However, these shapefiles were still very large and now the map on ArcGIS Explorer Online is unbearably slow. I wonder if it is just my shapefiles... I'll try different ones and update the map.
