Facebook Is Playing Peek-A-Boo With Me

It's there and then it's gone, and then it's there again, and then it's gone again.... this new virtual game is brought to you courtesy of Facebook.

I was relieved on Friday when my News Feed suddenly reappeared in its normal state, but on Saturday it stopped displaying more than 4 posts, and ending the page with the sentence I have now come to hate:
"There are no more posts to show right now."

What's going on here?

I can post from other applications, and these posts show up, like the one I did from Dagens Nyheter this morning, but trying to enter something directly through Facebook doesn't result in anything, at least not on my News Feed/TimeLine.
