I mostly agree. I don't have a problem getting some ads targeted based on the info I provide. What I DO mind is FB following me all around the web, so the one time I was bored and randomly clicked on some cheesy ad for something I would never buy, FB has decided I must love that and show me tons of retargeting or related ads.

The thing that is so f*ing frustrating about both FB and Google is they could provide REALLY good targeted ads by only looking at stuff I provide (e.g. my submitted profile info, my search keywords). Instead they have to track everything I do to squeeze an extra X% out of their conversion numbers.
