What would you teach aspiring journalists about the internet?

It’s officially official: I’m headed to Vancouver in January to spend a semester as the Canwest Global Visiting Professor at the University of British Columbia’s Graduate School of Journalism. I will be teaching online journalism as part of the school’s integrated journalism course.

I’m looking forward to helping students think critically about the internet as a platform for news, and I would appreciate suggestions on how best to do that. In other words, if you had this gig, what would you teach?
