No, no. The Pii have not all disappeared from the sidebar because they have all gone away. They simply are in process of moving from the good old Blogger to new heretical Blogger. Their Holinesses take their time in doing these things, you know. It's much like posting. They'll post when their rigorous schedules allow them time, and they, in their grace, deign it a fitting time to rant.
They'll be back.
