Is anyone else concerned about Facebook and other sites targeting ads?

Today I watched Pineapple Express. I searched it on Google and clicked on Wikipedia. I then clicked a link to a Wikipedia for Craig Robinson (actor). I log onto Facebook and there's an ad for Craig Robinson on the side. WTF? Am I the only one concerned about privacy issues here?

I'm only aware that ads can target keywords that appear as interests in your profile, I've not heard of search terms getting into ads. Perhaps that ad had appeared before but didn't penetrate your ad blindness, until CR was on your mind.

If I say Red Cars, Red Cars, Red Cars, what will you notice on your way to work that you usually overlook.

Facebook recently cautioned advertisers to not write ads or destination pages written for a search demographic, while you can target men 55 to 70 you can't say in the ad "Hey old guys"
