Anyone remember video w. prof talking about "dear Applicant" letter to his mom?

About learnings and the benefits of just clear english? I'm looking for it, but it is impossible to find on the internet. It came along here a month ago or so.<p>He talked about how business language corrupted english. About how his neighbours were insufficiently warned about forest fires because the warning did not explicitly say you would die if you stay.<p>About learnings, and ridiculous mission statements for schools.<p>Anyone remember it with a link? Why does HN not have a search? My wife is really interested in it but I cannot find it.
