Made up word? You've used it, so it's real now. I like it. There's a certain truthiness to it.

I think your argument is a compelling one. The richness and color of our language (and, if I may, I'll make the distinction between the varying forms of English here - not all variations embrace the tinted varietals of words) is largely due to this organic growth and change of its usage. While personally I don't use "comprised of" (that I know of - my memory is imperfect), I don't know that I'd choose to battle over the usage of the phrasing. I recognize that some common phrases evolve out of this sort of natural mutation of language.
