Currently diaspora needs both to display the location (as @svbergerem mentioned). But we can maybe make it optional and if there are no coordinates, just display the
address as text and don't add a map, and if there is no
address, we can display the coordinates as fallback. What do others think about that, should we loosen the constraints and use fallbacks instead?
But then you still need to wait until most of the pods use a version without that constraint, or your posts would be rejected.
