Hi, I graduated college with an undergraduate degree in Geography, specializing in GIS. My professional background is software development, and a few years back I transitioned into user experience design.<p>I'm wondering what, specifically, you're looking to "revolutionize." ESRI's suite is ugly, complicated and crash-prone compared to, say, Manifold, but Manifold has little traction in the market. It's like Word and OpenOffice.<p>GIS is a super-broad product category that support everything from photogrammetry to spatial analysis (think demographics, computing safety of bike paths, lines of sight for signage) across both vector and raster data with arbitrary reference points (did you know that most geographic data sets aren't globally georeferenced?).<p>Making a web-based clone of Powerpoint as an excuse to reinvent Objective C and Cocoa in JavaScript is comparatively easy. Your statement makes me skeptical that you know anything about the market at all.
