Emoticons
What is an emoticon? If you've been on the Internet for more than half an hour, you've probably already run across a few.

Why do people use emoticons? Well, for starters, the Internet is largely a text-based medium. Sometimes it can be hard to convey sarcasm or sincerity with only written words in email or chat.
