I was chatting to two of my very close friends today and understood the importance of Smileys in the electronic communication.
There is a research that states 70% of communication in humans is Non-verbal. The facial expressions and body language comprise of this non verbal communication and the words that we speak form the verbal communication.
Some words are very harsh in nature, but sometimes used in teasing, when coupled with smile. But, in case of e-communication, the other party can not see our expressions. Smileys are one great innovation in e-communication.
Currently, I am in so much love with the emoticons. ;)
