Why Can't MBA Students Write?

So my friend posted this article from the WSJ on her Facebook page today and I read it and thought I would share:

"Corporate hiring managers are increasingly complaining that M.B.A. grads have terrible writing skills, and more b-schools are trying to address the problem."

Sidenote - Tuck calls are rumored to be going out today and tomorrow!  I know the decisions will be released tomorrow in our accounts, so we shall see what happens.
