How could you NOT be interested in knowing where humans came from?
A religious upbringing, a lack of imagination, and a poor understanding of why abstract scientific endevours can be of practical use to mankind all help. That and having your head firmly planted up your posterior.
The "meet singles" is a little odd since I'm married, as are the "get a flat stomach" ads, for much the same reason.
Yeah, I wish the ads were more targeted for that very reason. No, I don't want to meet singles, you should know that.
The question is just how they learn these things, and if they use them for more nefarious purposes. With Facebook, I'm fine with them using the information that I gave them. I'm not fine with them using my activity outside the site to target advertising.
Nothing motivates a man more than to see his boss put in an honest day's work.
