The ESRI UC Blog is reporting that as of this afternoon 13,264 people were registered for the user conference. Thinking back to my first one back in Palm Springs I don’t think I could have imagined this many people. With Google Maps, Google Earth and other consumer GIS tools one can only think the conference will be getting even bigger next year (not to mention we’ll all have those great new ArcGIS 9.2 products in our hands).
