It's because I haven't received any more coupons that want to hit on me. Well, and because I blow my time reading "Lost" spoilers.
No, really, although the first of those two ideas is actually true, and that does leave me without as much interesting material to post, the simple truth is that I've been sitting with my notebook and thinking about what kind of book I'd like to put together next. (As for sitting with my notebook and actually writing in it -- that's easier some days than others).
Besides, everyone already knows that "Lost" is all in Hurley's head.
