Harvard econ professor, econ textbook author and sometimes New York Times columnist, Greg Mankiw points out that his Intro to Econ course, or Econ 10, is the largest course at Harvard.  Story here.

I wonder if Mankiw has given any thought to following in the footsteps of Sebastian Thrun and Peter Norvig, who taught their Stanford intro to computer science course online to 165,000 worldwide students.  Given the demand, Thrun gave up his tenure to start his own online university, Udacity, with novel goal of teaching people who want to learn how to program.

There are a few people who could stand to learn basic economics.  Perhaps Thrun has a spot for Mankiw on his faculty.
