A lot of people have been pointing me to this article on using blogs in writing classes instead of term papers. For an extensive answer, see my dissertation from 2007. Just sayin’. But yeah, communication forms change. That doesn’t mean we do away with argument and evidence and critical thinking. I mean, we used to give speeches (without teleprompters) all the time. We spoke poems. Now we have radio, tv, print articles, books, web sites, youtube, all kinds of ways of conveying an argument. We should teach all those.
