There used to be days when the combination of colon and right bracket would make the 'happy' smiley and the combination of colon and left bracket would make the 'sad' smiley! These were typically used in the conversation over SMSs. Later on there had been a successful creation of yellow smileys. And now a days, needless to say how many types of smileys or symbols are available in the smart phones! A lot of expressions have been converted into the smileys and more over the skin complexion has been added too! Tremendous creativity it is!
Innovation is one thing and the application is the actual thing. All of us have been using the smileys for different purposes in various conversations with friends, family, teachers, bosses etc. While some of the applications are too wise, some are too interesting, some are too sarcastic and etc.
Use a smiley.
