Not really related, but the last time I was on Facebook, its ads were so wrong I actually tried to improve it. It targeted me for endless hip hop ads. I don't like hip hop; nothing I've ever liked on FB had anything to do with hip hop. So, I told it I don't like these ads. Instead of trying to show me things that I might actually be even mildly interested in, it fed ever more hip hop ads to me. It was so aggravating, that I just closed FB out and I don't think I've ever logged in again.
