I'm not sure what happened. It's meant to be a facebook or twitter post of GLaDOS (of Portal fame) posting "Still Alive."
I suppose you didn't read the thread where facebook was permabanned
But it wasn't actually Facebook, just a link to a screenshot from Facebook that was up on another non-Faccebook site.
EDIT: Ah. it's from Tickled. They don't allow hotlinking. Hang on, I'll save it to my Photobucket...
There we go.
