Perhaps you can explain how I or anyone else will determine the
direction of this waterway: http://www.openstreetmap.org/?way=73765043
Should I ask one of the residents if I can go into their backyard and
dump food coloring in the water?

I don't know of any other feature where the direction of the way means
something *without* another tag being added. I've traced a number of
waterways from aerials and never had any idea I was supposed to set
the direction of the way equal to the direction of flow.
