Facebook Graph Search is live for me and it's scary

So, much to my surprise (as I'm just a random Belgian nobody) I noticed I had access to Graph Search when I logged into Facebook a few hours ago! I had some time experimenting with it and it's really, really scary actually. The amount of things you can do is insane, stalking people or finding a very specific set of people now got very, very easy.

They do throttle you if you search too much though. I've been trying a lot and now I don't get any result at all anymore, it'll probably start working again in a while.

Has anyone else already got access to Graph Search?
