@Grivusangel -- Preach it! These things drive me nuts. Right up there with using "to" as an intensifier instead of "too." Or when people write "would of" instead of "would have." I know we say it like that, but it's the contraction "would've," which is short for "would have."
I've seen the writing units kids do and they don't learn squat about grammar or good writing skills. We have a whole generation of numbskulls who can barely communicate in their mother tongue!
They don't know what a material noun is. They don't care what a material noun is. Knowing the parts of speech is not relevant to them. Don't get me started!
