I've enjoyed working on an enterprise, GIS-focused application over the past few years (with no prior, formal geographic background) and one of the take-aways I always enjoy sharing with family and friends is the "point in polygon" question [0] and it's simplicity. I'm fun at parties. I have certainly learned how much more intuitive data is for users to explore when you offer (if you can) spatially.
