Language is a living, breathing thing. Consider this verse:
Westron wynde, when wilt thou blow,
The small raine down can raine.
Cryst, if my love were in my armes
And I in my bedde again!
My Oxford Anthology attributes the verse to Anonymous, somewhere in the 13th century or so.
So, in the space of a few centuries, we've altered some spelling (and, according to scholars, more than some pronunciation). But the visceral meaning of the verse, and the almost tangible longing of the author, remains today.
Which is not to say that a few centuries from now, this verse and this post will be as unintelligible to the people of that time as Old English is to the vast majority of us today. Language evolves as surely as does life.
However, there's nothing wrong with defending the current convention and the formality of standard English. Hell, I was an English major, and I'm aghast at much of the communication I see from my peers. There's a place for idiomatic patter; neither the business world nor the arena of ideas is that place.

Agreed, Judy, that No Child Left Behind programs will usher in the death of critical thinking. This country doesn't need rote automatons. We need analytical, critical thinkers with the tools to solve thorny and important issues. The purpose of education, especially childhood education, should be to exercise the mind and teach the student how to think, not what to think, or what to memorize.
"When I think back on all the crap I learned in high school
It's a wonder I can think at all."
