Hahhaha, that's funny. However, I found another purpose. I'm actually interested in seeing some of the things those "friends that I barely know" post on their facebook pages. Also interested in commenting / interacting from time to time. Impossible if they're not in your friends list.

Do I want their stuff cluttering up my news feed? No. Do I want them seeing everything I post, especially things that are really only intended for friends and/or family? No. Thankfully that doesn't have to happen.
