An information organization system that is discoverable but not searchable
forms neither exactly a lightnet nor a darknet. Nothing is totally hidden, but
neither is it entirely revealed. It is a liminal thing, a twilight net.

One of the cardinal virtues of the twilight network structure is the sense of
novel discovery, of finding old rings of unknown provenance hidden between the
cracks in the floorboards. The history of the world may be found there, 
dust-buried, untouched. It is because it is untouched that it is intact.

There is something deep-seated in the human psyche that responds to secrets, to
still places, to ruined buildings and wilderness. The sense of being the first
human to pass through a place in a hundred years, of being the only moving thing
among dust-shelves holding their breath, makes us feel something that occurs
nowhere else.
