English teachers wrong? Imnpossible!

"Here’s a chilling thought: What if our English teachers were wrong? Maybe not about everything, but about a few memorable lessons. " 

I found an interesting (and relevant) debate over at the New York Times about grammar rules.  Read both sides of the argument and in one blog entry choose a side. You should also define important terms (i.e, descriptivist, and prescriptivist). It might be a good idea to look at what rhetorical modes they're manipulating.
