The site is currently vacant from the looks of it. What happened to it? Will it be back up? This doesn't look good.

Chances are the same thing that happens to most websites that are run by individuals and not businesses. Subscriptions probably dropped off, Michelle may have lost interest in posting things online (low subs, may mean low interest, which could mean that it souldnt be financially viable to continue the site). This happens to a lot of sites over time.
