Cheaters, sexters and ugly selfie fans can rejoice. Snapchat, the app that self-destructs photos and messages, unveiled text messaging and video chat features today that will allow users to carry on seamless conversations with friends who are using the app at the same time. Many users had previously sent multiple videos and photos back and forth to carry on a conversation. The new features work by eliminating the piece mill process and giving users the full attention of their friends who are also on the app.
