EM One thing that attracts me is the pattern of communication here. In BBS, The posters and commenters are weighted the same (compared with WeChat official accounts, where comments are filtered by the authors), and users here are encouraged to build conversations in the form of long texts, being able to share valuable and structured information or knowledge. This is different from that of Weibo, Zhihu, or instant messaging apps. This could be a place for serious discussion while also keeping the functionality of doing idle chats.
