Not everyone is drawn to participate and engage in online communities, and age and lifestyle often discourage people from getting involved. According to Dorine C. Andrews, author of Audience-Specific Online Community Design there are three parts to building an online community: starting the online community, encouraging early online interaction, and moving to a self-sustaining interactive environment.[24] When starting an online community, it may be effective to create webpages that appeal to specific interests. Online communities with clear topics and easy access tend to be most effective. In order to gain early interaction by members, privacy guarantees and interwoven content discussion are very important.[25] Successful online communities tend to be able to function self-sufficiently.[26]
