Not quite a sequel, but he recently gave more details on the post-phd transition here: http://pgbovine.net/one-weird-year.htm.
Is it just that he's on the other side of the advisor-student power-balance? Or that he has the experience and skills to negotiate them better?
Since he's now familiar with and known in his chosen area, he may honestly be able to say to his students "I can help you do meaningful and rewarding research".
(Of course, I dunno what the actual story is.)
