Love the emoticons. But how about a sense of proportion about using them?
Some of them are turning into the smiley face equivalent of LOL.
To my mind should be used sparingly, when someone says something so genuinely funny, perceptive or incisively sarcastic that you nearly get a hernia from laughing, and not just as a punctuation mark.
And frankly, posting a reply with JUST an emoticon should have you banned for a week.
