The silence of the Klam

Following up on my Lauryn Hill question (and thanks much, Scott Cunningham, for the detailed answer there): what’s the deal with Matthew Klam. The stories in “Sam the Cat” (2001) are hilarious, and they also give the impression that Klam could just whip them out. Since then, though . . . almost nothing. Klam has a bizarrely professional-looking webpage but not the output I’d expect. What’s the deal? Maybe author/blogger J. Robert Lennon knows?
