Redesigning the country selector
On a similar note, I've always found it kind of amusing/frustrating that forms in the US make you fill out city, state, and zip code, when in fact the zip code indicates a specific city and state.  I realize that's a huge database of geolocation data to keep as part of the program, but I wonder if there could be some kind of lookup that goes on behind the scenes and fills in the city and state if the response is quick enough (and allows the user to fill it in manually if it doesn't).
