"who's" = "who is"

"whose" = The possessive form of "who" (or "which", says AHD4)

I've seen so many intelligent people make this mistake TODAY that it's (not "its", notice) driving me bugfuck.

I usually go for the Bob The Angry Flower strips, myself. :)

Actually, the Apostrophe Protection Society is mistaken in one regard. There are in fact several cases wherein it is legal to use an apostrophe for pluralization. Single letters, acronyms, numbers, and occasionally very short words are all considered legal targets for apostrophic pluralization (I just made up that term, but doesn't it sound cool?).

So "CD's" and "1000's" are actually both legal (though it is equally legal, and I believe now preferable, not to use apostrophes in those cases). I do always use apostrophes when pluralizing letters: "mind your p's and q's" being the typical example.

The APS isn't so much incorrect as British.
