Google Earth has struck up a huge wave of interest in GIS and spatial mapping capabilities. Most users of GE are not yet aware of the tremendous additions the GIS industry is going to add to this new wave in spatial information - but I am sure that ESRI's ArcGIS Explorer is going to change all that.

Market forces are working their magic. ESRI products are superior to most, (and because of that) they are able to charge practically whatever they like for their products. It took a mammoth search engine giant (in Google) to stir the pot a bit in the geospatial industry, and ESRI responded by cooking something free up.

Soon, everyone will be performing spatial queries and analyzing statistics of our own data using ArcGIS Explorer. We'll also be using other's data. The spirit of ArcDex (short for Arc Index, and inspired by MapDex) the theory that we all have shapefiles that can be shared among all users . We all have cool tips, tricks, and hints to make ArcGIS Explorer fun and useful. I hope to feature and catalog as much of this information as possible, to encourage a broad range of collaboration.
