If you look to the left of the picture, you will see that there's an apparently random selection of articles ImaginaryFriend has recommended. If you look to the left of this article, I assume you'll see what I've recommended. It feels kind of stalker-esque to me. I almost never look at the left column, so I don't know how long ago it was added. Maybe this has always been there. If that's the case, I guess I'm okay with it.
EDIT: I guess what I dislike isn't so much that people see what I've recommended as random people may see one of my posts if it gets recommended. It also feels like I'm doing the stalking looking at other people's recommends, but I can deal with that.
