Specifically, I take issue with NG's foreign accent. That's just me looking for a reason, but it's the second time after Agarwal on MITx (and that wanted me to purchase his book). Also, I can already record lectures and play them back at will, only I have to leave the house for that. Besides that, these courses were rather classical university courses, it seems.

My gripe is, the videos are too long and my attention span too short. The first 2 weeks I could even pass just from what I learned reading HN, so I suppose I really prefer the socratic method instead of frontal education. Many would claim I was simply lazy and they'd be right, alas also derogitory.
