论文摘要
大规模的定量分析表明，个人经常在不同的在线空间中互相谈论类似事物。为什么存在这些重叠的社区？我们在分析了对高度相关子列表集群中的20个活跃参与者的访谈分析中提供的答案。在广泛的主题领域，在线社区可以授予各种好处。其中包括（a）特定信息和讨论，（b）与其他人的社交，以及（c）最大受众的关注。一个社区无法满足所有三个需求。我们的发现表明，在线社区平台内的主题领域往往会被各种规模，局部界限和规则的专业社区组成。与任何单一社区相比，重叠社区的系统能够提供更大的好处。
Large-scale quantitative analyses have shown that individuals frequently talk to each other about similar things in different online spaces. Why do these overlapping communities exist? We provide an answer grounded in the analysis of 20 interviews with active participants in clusters of highly related subreddits. Within a broad topical area, there are a diversity of benefits an online community can confer. These include (a) specific information and discussion, (b) socialization with similar others, and (c) attention from the largest possible audience. A single community cannot meet all three needs. Our findings suggest that topical areas within an online community platform tend to become populated by groups of specialized communities with diverse sizes, topical boundaries, and rules. Compared with any single community, such systems of overlapping communities are able to provide a greater range of benefits.
