I can't think of a more appropriate use of citizen journalism than paparazzi. Why? Because the context and veracity of a photo of actor X in sweatpants makes no difference. It's merely the image that counts. And if some random dude is lucky enough to photograph Suri Cruise with his cellphone, then more power to him.
