``Hair'' tends to mean more than ``hairs'', but you leave out the correct analogy of ``a hair''. Interesting nonetheless.

The verbal complexity of ``WWW'' versus it's ``longer'' form is interesting, and hadn't quite occurred to me before. An interesting thing to note is that the most significant shortening by abbreviation is that of ``El Pueblo de Nuestra Senora la Reina de los Angeles de Porciuncula'' to ``LA'' (not that the city has gone by that name in hundreds of years).

But, given that ``zenzizenzizenzic'' isn't in the Oxford English Dictionary, I'll have to call foul on that one.
