From what I understand, FB's new rules start today. I believe it has to do with who and what appears on your timeline/news feed, but I didn't get it all. So I'm going to different friends' page, and under 'like' or 'follow' or 'friends' I'm checking 'Get Notifications' to make sure their posts appear on my news feed. I'm not sure that will take care of the changes, and I'm sure I'll miss a few, but I hope this will help.
