If you haven’t heard, facebook has rolled out(or maybe is in the process of rolling out. I’m not sure if everyone’s got it) Friendship pages which “tell the story between 2 people”
You can test out this feature by going to a friend’s profile page and just under his profile picture is a button “View You and XYZ”. You can also view friendship pages of any 2 people so long as you have permission to view their walls.
While I think it’s actually pretty cool to be able to look back on all the events I’ve been to with someone, all the past wall messages and the common things we like, I think this just upped the creepy stalker factor by another notch.
My advice: Learn how to manage your privacy settings people. And teach others to do the same.
