I wouldn't say the UX challenges get any easier as you grow from social networking "super app" to generalized "super app." If anything, it would become more challenging, and the top comment would make more sense as to how it appears intuitive.
On the topic of social, though, WeChat has private messaging and broadcasting, location sharing, a social feed of friends' updates, and public accounts that can push feeds to subscribers [1]. Mediums include text, voice, photo, video, and location, all shared through a variety of types of feeds.
