I'm convinced that the delivery systems just need to improve. I was lukewarm on audiobooks and podcasts when I needed to manage syncing them in iTunes - with Audible's excellent app and a solid podcast app (Instacast), I've been consuming both voraciously. iTunes U is awkward, buried in that monstrosity of a program that most of us avoid using when possible. "iTunes" is even slow and convoluted on the iPhone - you need to download the course (and, no, you're not notified when new courses come out) and play the video in a separate app. Something simple along the lines of the better podcasting apps (maybe with some means of attaching/tracking homework?) would make this much more addictive. They don't need gimmicks, they need to stop sucking.
