A couple other oddities of geography I have noticed as a geospatial system developer.

- Outside the US and Europe things tend to get really wacky with geography and geospatial data. Many GIS products are licensed per country for this very reason.

- In the US, zip codes are the most terrible type of geography to use for any meaningful analysis, as they are constantly changing and do not actually have defined borders. Zip codes are basically just labels that get appended to street segments.

- If you look in the back of the ~200 page pdf that comes with most digital geographic data, you will find an appendix. 99% of the appendix is a section typically called "disputed territories", and 99% of the disputed territories are China claiming to own another nation. I never realized quite the extent of the megalomania until I read a few of those.
