The location of where I live, or the location of where I work? What about when travelling on work to a far off city? A single field isn't enough.

For example, the only other Maemo user near home is my wife (and son), AFAIK. In London, we've got lots of people (crashanddie, qwerty12, anidel, etc.). In Sweden, there's Jeremiah - but Gothenberg's not that close to Stockholm (AFAIK).
