Your link looks interesting, and is not seeming too wild-eyed.

"23 CD lecture" is a time investment that I might not make without a convincing sales pitch that addresses my own needs, though, not entirely just the needs of the lecturer.

By "not wild eyed", I mean I could agree with the drift that I did see in it.

To engage me, though, you need to go out on a limb with your own specific spin(s), something that you are at least willing to temporarily defend.
