Everything communicates: our posture, our gestures, even our silence, communicates. When we talk about communication, not only two elements intervene: the sender and the receiver, but other elements such as the context, the channel, the language, the barriers and even the intention we have to communicate or not. It is easy to perceive when a person can be sad, tired or happy and excited just by seeing him walk, talk, interact with the other. That is to say, if the communication in personal, person apersona. But sometimes, communication through digital media, can not be as effective, however, have sought ways to make the messages are increasingly clear (use of capital letters, quotes, gifs and emoticons). I have witnessed several discussions because they have not known how to code the message because they do not handle language or codes well. In defense of man, always, since the world is world, man has sought the way to communicate. Perhaps at some moment he will achieve perfection. Greetings and thank you, @tarazkp
