No, my not was about basic physics, admittedly a bit pedantic:
As most waterfalls have a horizontal movement component  in addition to the
component caused by gravity, the point where the falling water hits the
ground is not exactly bellow the point where it starts its fall.

In addition, there is the more practical issue that often what is called a
waterfall is a series of cascades.

+1, while I'd consider your first point bike shedding, this second point is
indeed important for mapping waterfalls, hence the suggestion to use both,
waterway=waterfall for the single cascade and natural=waterfall as a
comprehensive area for what is a named waterfall, i.e. together with name,
wikipedia and other tags that apply to the entire waterfall (e.g. height,
maximum of water per second passing or whatever else might be interesting
and taggable).

cheers,
Martin

In UK english, a series of waterfalls are called falls.

World English Dictionary: waterfall: a cascade of falling water where there is 
a vertical or almost vertical step in a river.

Maybe you are thinking of a series of waterfalls or a rapids or a combination 
of the two as a "waterfall"?

Niagara Falls are tagged as area with tag waterway=waterfall + natural=cliff.

For me waterway=waterfall is better for node or segment of waterway. Or with
key waterfall=yes

And natural=waterfall is better for large river that use riverbank. Only for
way or area. Render as cliff but blue.

Without the link to the proposal I can only guess, but perhaps it still
contains this template:

http://wiki.openstreetmap.org/wiki/Template:Post-vote_clean-up

It automatically inserts a page into the "Post-vote clean-up" category.

Well it is tagged as site. The American Fall is tagged as
waterway=waterfall as node in a way with natural=cliff plus an area with
waterway=waterfall and natural=cliff, the Horseshoe Fall is tagged as
node with waterway=waterfall and a way as cliff

The Victory Falls are tagged similar to the Horseshoe Fall and not
divided but should be.

+1

but they are called falls (natural=waterfalls ?).

I am not sure if we can judge the definition by only looking at these
big examples.

Think about kajaks and white water sports.

Major problem once more is documentation.
