Although its primary prevalence is found in Korea, its influence has spread over China in recent years. Cyworld users range anywhere from elementary students to middle-aged adults. Cyworld requires a person's real identity (Koreans: verified by Korean national identification number (주민등록번호); Foreigners: scanned school/state ID, driver's license, or passport) to become a member. Since all identity is usually truthful and non-anonymous, users often use this to seek lost friends from childhood or former classmates on the website, or make and progress their friendship by system that called by 'mini-homepage (minihompy, 미니홈피)'. Similar to blogs, many people share their thoughts and photos that other friends (called 일촌, il-chon) can comment on. A typical 'mini-homepage' features a main page, a photographic album, a guest book, and a personal diary. Users are given many choices for personalizing their pages with music, backgrounds, and even fonts. One of the major differences between Cyworld and blogs is that Cyworld is optimized for the users who prefer to write very short and succinct diaries. One popular personalized feature is the 'mini-room (미니룸)', where a user is given a single rectangular room to decorate with different objects. These objects (as well as personalized features) are bought with online dollars called dotori (acorn, in English). Every user is given a 'mini-me (미니미)', a caricature. Although each user is given a prototype, gender-appropriate figure, they liberally personalize these figures with a variety of dress and hairstyle options. Because the website contains mostly truthful information, social issues have been raised such as Cyber-bullying.
