I talked for about a minute with Ann (Dave's wife) a while ago, and apparently Dave has ceased updating the comic because he doesn't have the time. I do not know when (or even if) he plans to start updating again, though I do hope he does.
Well, it's nice to at least know that Dave is well. I didn't know if the updates stopped due to scheduling or the weather getting nicer.
VL was about my fave KS webcomic out there. And I do check the Keenspace guide fairly regularly to see if Dave has started to share with us again. Even if that never happens, it was a well-written run of comicy goodness.
