A comparison which tells us what exactly?  Does checking out a Youtube 
clip compare to attending lectures at UCB?  The throw-way remark strikes 
me as typical of the category errors that increasingly beset 
commentators as they try to make fast sense of the latest fad before the 
next fad rolls in. 

And how do we know that most Youtube viewers haven't watched the first 
15 secs, realised that the lecture isn't as interesting as the baby 
biting his brother, and moved on?
