Maybe the fellow is just really, really busy with life, whether related to QLI or not.
Or, maybe, after working at running a Traveller business, he finds that in his "off" time, he really doesn't feel like discussing Traveller or finds that he needs a chance to devote energies elsewhere to relax.
I love what I do professionally (interaction design), and I enjoy working. But, that said, I don't want to spend my evenings and weekends discussing or doing interaction design. It's fine occasionally, but I want to do other things with my non working time.
Wouldn't be a good thing (for the Traveller community, at least) for Hunter to follow in Joe Fugate's footsteps: immerse himself in Traveller and running a Traveller business so much that he eventually gets sick of it and finds that he doesn't like the course his life has taken.
