Facebook now tells people who has visited their pages

What is the point of Facebook if you can't stalk your eighth-grade boyfriend or see how fat your loathed high school nemesis got? Apparently Facebook execs don’t understand that anonymously keeping tabs on unassuming acquaintances is half the fun of the social network, which announced today that starting yesterday (do you like how they tell us too late?), people can see who has viewed posts in group pages. So for instance, if you're curious who else was invited to an event and happen to visit the page, all other invitees can see exactly who and what you clicked. The invasive new mechanism hasn’t yet extended to the rest of the site yet, but along with the news that Facebook monitors your chats, it seems like a frighteningly slippery slope to us. [Source]
