The social-networking service earlier this month began posting updates about users' activities on Web sites outside of Facebook and on commercial pages within Facebook -- in some cases, alongside ads from the companies behind those Web sites or pages. Facebook is posting users' photos alongside certain advertisements, another feature that has alarmed some privacy advocates and users. For instance, a user who logs on to Facebook might see an update in a section of the site called the "news feed" noting the movie a friend rented from an online site, along with a photo of that friend and a movie-rental ad. http://online.wsj.com/article/SB119560466428899897.html
Thats a bit weird. I wouldn't like that. Good job i'm not on facebook. ps are you even allowed to post pictures next to advertisements (thus highlighting them for people to click more)? I'm sure adsense doesn't allow it for a start.
