I'm going to pass on listening to this -- it's a super busy week -- on the grounds that I just finished Michael Lewis' book and I'm probably covered, right?

The instructor knew more than could be hoped, to be fair -- middle-aged, loaded Norwegian guy, very smart, very good class -- but he was pro- ... and try as they may for bipartisanship, it's not possible for professors. 90 percent of the class was hearing about HFT for the first time, and now the only thing they'll say when they explain it to even more ignorant people is "it creates market efficiency." Shit.
