Before social networking, there was instant messaging. The most popular was brought to us by none other than AOL. Remember AIM? If you were ever a student in the late 90's or early 00's with an internet connection, then of course you do. Now, Facebook is bringing a little piece of nostalgia back with a new feature called "sidebar status." It's eerily similar to the "away message" of yesteryear and is a way to let your friends know what you're doing when you go AFK.
