I've got to say that in 3 years of facebook, I've never seen anyone change their actual location unless they were full out moving somewhere - so I don't really see a need for this at all (unless it is targeted for when people move... but how often is that?)
Now if this was based on Facebook check-ins (or foursquare for that matter) then THAT would be useful (i.e. if certain friends "checked in" near my place and didn't say hi I'd be interested)
