If you are logged into Facebook and simply go to the CNN site you are presented with a list of your friends that already Liked or Recommended that site. This means that Facebook already knows you are watching this page even though you took no action. Yes, you can remove the item from your news feed, but it also appears in your Page | Info list as well. This can only be removed from the original site (AFAIK). My concern is that it's getting harder to have meaningful discussions for fear of future ramifications. Abortion? Gay marriage? Stem cell research? Can I only talk about those topics offline now? Can I read online articles on those topics if I'm logged into Facebook without it being tracked?
