During life transitions, people sometimes turn to social media audiences separate from their typical online networks. By qualitatively analyzing open-ended data from a U.S.-based survey (N = 775), we examined why and how people discuss life transitions with these separate audiences. Survey questions asked about life events experienced, separate networks and the interactions that occurred there, and participants' reasoning behind these online behaviors. We found that people use separate networks, especially online support groups, to interact with others anonymously, receive informational and emotional support, and have direct and focused discussions with people with similar experiences.
