Most folks these days are more interested in enrolling in one of Lo's classes for the future contact, not the course content.
I remember walking by Lo one afternoon and overhearing a medical doctor trying to catch up with him in order to tell him what a "lifetime admirer" he has been of Lo's work. It could have been anything from Lo's latest antics claiming that he knows how to "harness the power of greed" to cure cancer (the so-called Cancer-X project) to this poor fellow thinking that he had discovered a new way of beating the stock market (perhaps after reading this classy title that Lo published with one of his more attractive acolytes several years ago: The Heretics of Finance.)
