Inside Higher Ed has an interesting article about Open Instruction (it is not really open source, as that refers specifically to software that is collaborative created and maintained).
I say yay. Bring it. All of it. Let me see the lectures, read the materials, and gain access to the information. I will not get the official credit. My transcripts will not be Ivy, but I will finally be able to hear the discourse previously only available in peer-reviewed journals.
<>Individual instructors will expand their cults of personality, eventually a few of them breaking into celebrity (of a lower level) status.
Still, not a bad thing.
