People who chat on-line have different reasons--there are people killing time, people making friends, people looking for friends of the opposite sex, people looking for sexual partners, people getting things off their chest, newcomers, people practicing their Chinese typing, etc.
網路聊天族約略分為幾種類型：消磨時間、結交朋友、尋找異性、尋找性伴侶、吐露心事、新手上路、練習中文打字速度等。
