What happened to Jon Katz?

Blob Pet writes: A few years back Jon Katz disappeared from Slashdot. I don't remember if there was any formal announcement made, but at some point I did notice that I hadn't seen any of his diatribes in quite some time. Well, according to CNN, Katz has apparently been writing books about his border-collie Orson who apparently changed his life. His first book, "A Dog Year," is being made into a movie.
