We ask what factors cause a blogger to continue participating in the community by contributing content (e.g., posts, comments). We crawled a sample of blogger profiles (contributed 91% posts) from a popular community blogging platform \Blogster". Our results show that the male and aged (senior) bloggers, who face fewer constraints and have more opportunities in the community are more retained than others. Other bloggers pay a high degree of attention to these retained bloggers through implicit (reading posts) and explicit (writing comments) interactions. We have also found that a blogger has higher retention if her friends have also higher retention and a strong social tie reduces retention imbalance between two blogger friends. However, we found that a blogger's network age (e.g., how long ago she joined) has no effect on her retention.
