"Who are the Habbo Hotel users, and what is so important in this virtual world that one quarter of the Finnish 10-15 years old population like to spend time there regularly? We present user categorisations based on empirical data from participant observations, a sur-vey, user interviews, and fansite articles. Our results show a learning curve of about 3-4 months in average regarding Habbo behaviour and opinions, and we found some correla-tions between demographics (mainly age and gender) and online activities. The study found no single motivation for Habbo use, but instead points towards diversity, open-ended use, and creative content production. The users take part in the innovation process, since what active users do in Habbo becomes both a fundamental part of the use experience and a source of inspiration for the Habbo developers." - Research Gate
