People need to understand OCW and Khan Academy serve two very different purposes. OCW was made to make the awesome materials generated by MIT profs to the general public, while Khan Academy was made specifically for the purpose of giving personalised learning. In my view both of them are noble causes and non of them should be abandoned, you can teach very less material in 10 mins after you cross the K 12 level. For covering one lesson in at the undergraduate level you definitely need at least half an hour.
