I like the concept of 'walkouts.' And I'd add they don't necessarily reflect badly on those being walked out on - sometimes they're just the result of a disconnect between what a person thought they were getting into and what it turned out they actually getting. As the author mentioned, walkouts occur more when there's no incremental cost in walking out, so I've seen them a lot at sessions for conferences that have a fixed registration fee - e.g., a presentation may be great but just over one's head. Imagine walkouts must really be prevalent in free MOOCs (how many college courses would you have dropped had there been no consequences?).
