Where are these folks? Am I just looking in the wrong places?

Hey Geoff! Howya doin'? The interesting thing about this question is that the people who can give you the real answers about where they are and what's happened to them, are the very ones you're searching for. For any of the rest of us, it's kinda like passing on "heresay" information. I know I've seen some of these people around, but I'm not sure how long ago it was. I definitely don't know why someone else may not be around any more. You could always try PMing them? It's nice that you're concerned about them.

Happy hunting, Geoff!
