Administrator-users contribute more to online communities
研究提出并检验了培养意见领袖和允许用户发布非主题文章的策略，发现鼓励用户担任管理员角色能显著增加他们对公共空间和个人空间的贡献。
Lack of user participation and contribution has been a long-standing problem for online communities. We proposed and examined new strategies for cultivating opinion leadership and enabling users to post articles outside of the community theme. We used social role theory to propose that online communities should encourage highly committed users to take administrator roles, which will increase their opinion leadership and contributions to both public spaces and their own user-controlled spaces. We collected multiple-wave and multiple-source data from 1,115 users of a large online community. The results indicate that encouraging users to take administrator roles increases their community contributions.
