" the lecture or talk is a waste of time if it's not recorded and put up on YouTube, as many more people will watch online than offline."
"Unlike education, the web has a habit of producing pedagogic models that have massive user adoption. Short, instructive video is one such Massive Open Online Pedagogy (MOOP). YouTube showed that short, video clips have a serious contribution to play in learning. YouTube EDU put lectures online but if anything this was the old world porting its old bad practices into the new world. A bad one hour lecture isn't made better by putting it on YouTube and believe me, YouTube EDU is jammed with bad lectures"
