topics in Brightkite tagged with turn of fields

For Belgium (and some other countries in europe as well) it would be handy if you could turn of the 'state' field in a location, as we don't use. We just have city, postcode and country. (Although we use 'province' , google seem to handle them different).
It gives very strange location titles ex.:
Koningsstraat 39, 8400 Oostende, Oostende, Belgium (Koningsstraat 39, Oostende, Vlaams Gewest 8400, BE).

Could be nice for some places, we don't have to display the street itself too, as street is not always relevant (woods, beach, ...)
