literacy/oral presentations

I have to admit to occasionally raving about trying to teach literature to a post-literate generation.  However, if you can believe Clive Thompson and the data of the Stanford Study, at least students are writing more avidly than ever AND they are more conscious of the business of writing for an audience.  An older stance is that you learn to write well by reading.  And if students are more conscious of audience, does this carry on into presenting orally to an audience? Some interesting implications, perhaps?
