“Creating successful online social spaces requires attention to usability and sociability. Online social interaction involves individuals interacting with the technology (i.e., usability) and with each other via the technology (i.e., sociability). Attending to issues such as how users create and send messages, and communicate non-verbal cues are examples of usability design; attending to moderation, facilitation, politeness, leadership, and social support online are examples of sociability design. Both are needed for thriving social interaction online.” (Jenny Preece – Oxford Internet Institute)
