I don't entirely agree with the assertion that you cannot charge for content. E.g. "It is probably harder to make a living selling lectures than it is as a journalist, and it has become nearly impossible to live off journalism." I made a substantial chunk of change this year delivering training. The difference is people can directly connect training to revenue. In my case I'm teaching Scala, where my course attendees either need it for their job, and know that getting Scala on their resume will open up some very well paying gigs. In this situation people will pay for a directed introduction to a topic, and also to clear the time on their schedule. The problem faced by good Universities face is that they are teaching foundations not ephemera, and most people have difficulty connecting the dots from learning, say, mathematics, to revenue. Which is a real shame, because foundations are far more valuable in the long term. FWIW, our Scala courses try to sneak in foundational material while no-one is looking. :)
