As you probably noticed, I use emoticons (a pictorial representation of a facial expression) very often. Mostly only two of them: a smiling face :-)and a sad face 😦 . Sometimes I also use a wink ;-). I like emoticons as for me they make written text less formal and more personal. And it looks like there are plenty of people who think the same. In 2007, a Yahoo! surveyed 40,000 Yahoo! Messenger users and found that 82% of them used emoticons in their IM conversations.
I wonder however how the world would look if people winked in real life as much as they do online 😉
