What's wrong with GFC??

I don't know if anyone knows the answer to this, maybe one of the more tech-savvie bloggers?

I can't seem to join any blogs with GFC any more (my own followers are still displayed). Whenever I try to join a blog, it always tells me to sign in (even though I'm signed in already)

I've tried different blogs - doesn't make a difference. So frustrating!! Making contact is one of my main pleasures of blogging arrrgh. Anyone got any clue? It's been like that for several days now. Or otherwise thanks for listening to my rant, and I'm not deliberately trying to ignore your blogs
