So has there been someone that tried to sue themselves, yet? Just curious.
Really though, Wikipedia and Craigslist? No. Try just about every non-business related social networking website (Facebook, MySpace, Twitter, Stickam, Formspring), every phone company (for "sexting), every E-mail service (file attachments), every website that allows you to stream your webcam (chatroulette, cam4, oovoo, meebo, etc.) and all the makers of webcams and camera phones. Hell, lets dig up the grave of the guy that invented the camera and sue his @$$.
