Social is the activity hearth at Social in the nav — posts from members you follow, communities you joined, and a For You mix when the site has enough signal.
Tabs typically include For You, Following, and Communities. Clicking a post opens a focus view with comments and appreciations (the ember react). Member follows are one-way; Friends are mutual and unlock easier messaging when privacy allows.
Social is for people and posts. Story discovery still lives on Home, Explore, and Collections. Side nav keeps Communities, Messages, and Profile one hop away.
Create a community from the Communities hub when you want a lasting club — story discussion boards remain available on each serial for chapter-by-chapter talk.
