It's only creepy if the personalization is tacked on and out of place. If integration were done in a meaningful manner, for example if you were on a site and you wished you could see the site in the context of your social circle, then such integration probably wouldn't be creepy. It would done in such a way where the integration is part of the core value offer.
But say I'm reading an article and it says "your mother likes this too," well to me it doesn't add much to the site. So what's left is the creepy factor naked and exposed. I guess that's why there's the RFS: so we can find more useful integration of facebook. But as soon as it's useful no one will think creepy. Creepy is the ugly girl who stares at you, but the pretty one who does it isn't.

I'm not sure it's just that. A big factor in the creepy feeling is the unexpectedness. You don't, generally, expect most websites to know who you are and what your social circle is. And if they are, unexpectedly, it feels creepy. I understand that Facebook's idea is 'one day, it will be so common, it won't be creepy'. They may well be right but it seems like a tremendously high hurdle to overcome, to me.
