Off topic.
http://wiki.openstreetmap.org/wiki/Proposed_features/Harbour#Quay .. is 
dated .. 2008 or before .. 8 years ? proposed? Ridiculous! Abandoned .. 
why? And what is used in its place? Very poor documentation - nothing 
directly on why it failed.

================

  One could also use waterway=quay or waterway=wharf. This would 
associate it with a waterway, might be a natural feature (think of a 
solid sandstone bank used as a wharf), or man made so why not waterway?  
Does not sit with man_made=pier .. but those don't occur as natural 
features? My thinking is to follow highway=* tagging where traffic 
lights are tagged hightway=traffic_lights rather than 
man_made=traffic_lights. This groups things together for a more logical 
system of things that would be associated all in the one main tag.

-----------
As the coastline in some places is man made .. I'd much rather see 
coastline as waterway=coastline rather than natural=coastline. This 
comes back to my thoughts on OSM tagging philosophy/thinking/order ...
