This entry from the Harvard Business Review Blog
Google Doc: The original article I Won’t Hire People Who Use Poor Grammar provoked an interesting discussion on Reddit. I’ve brought the two together in the google doc.
The discussion features a wide variety of points of view. I think the topic is useful both as an example of why grammar can matter (I’d add the concept of purpose and audience to the discussion), and also as an example of reasoned argument. The Reddit discussion could be contrasted with other internet “commentary” that quickly degenerates into name calling.
