I got that too. Any screenshots or examples of what this looks like?
Well, now I took a closer look I'm seeing private photos switching back and forth. I'm waiting for a friend to confirm, but I see photos I posted to closed groups that have no relevance to others out of context. I'm waiting for a friend to tell me what he sees.
Refreshingly empty. I use Facebook as a last resort to contact friends and was pleased to see they didn't drag anyone else's year-in-review into mine.
