Can I take a look at your product? I would be curious what a minimal ArcGIS would look like and how long it would take to build. GIS is super edge-casey, I think.
No sorry. I've created too embarrassing a trail of HN comments to want to link this identity to my livelihood. But it's not actually GIS, just a similar sort of product. It might be that an equally minimal GIS really too feature-poor to be any use at all.
