Yup, I went in to my blogger dashboard to add a few posts for next week, and there they all were, sitting in the stack. The funny thing is - they all said "Scheduled" for dates that had already occurred.
I don't know what happened.
Anyway, I've rescheduled them for this coming week. I'll try to keep a closer eye and make sure they actually show up ('cause some of 'em are kinda cool!)
