I get the analogy. But it's wrong. Phil Hill explains his thinking: "Everyone has them and needs them, but there’s a certain shame having one in the driveway." Well, OK. But of course the LMS is more like a bus than a minivan - someone else is driving, it only travels on a pre-arranged route, the bus is often late but you still have to be on time because it won't wait if you miss it. But in a deeper and more important sense, he's right (and least for his community): "the LMS is important and ubiquitous, but we all know we need better options. Despite this, take away the LMS and see if students like a different method to submit assignments or check grades for every class."
