When MySpace started to get too spam-y, and Facebook applications got downright annoying, Twitter stepped in and straight changed the social-networking game. Not only did the mass-conversation aspect connect people they've never met before, it's also become a source for breaking news, and a way for fans to interact with their favorite celebrities, all in 140 characters or less. Way too high on a list like this for something that just caught on a year or so ago? What other products do you, your mom, your boss, and CNN all use on a daily basis? FOH.
