This is where maybe a Treeview option on a post might be an interesting idea to be able to switch from viewing the entire topic to seeing a chain tree that originates from a single post with option to switch back to standard flat model.
I am used to the flat model since the early days of DOS BBS programs. However in this modern age can see a benefit to be able switch to a thread model whem wanting to follow a specific flow of posts.
Add tagline to your post and any place could have it. On Discourse there is even the Nostalgic Signatures plugin.
Now if one wants to post system specs on each post Hide Details is likely a nicer idea for a tagline as it can be less clutter this way. Depending on the forum having a user’s specs is very beneficial ie Troubleshooting pc issues, as often I know in my case usually have to ask the user to post this info. 
Reddit 关于新闻、快速回复和有时复杂的词语！而 Discourse 则是关于社区和高质量内容。我仍然使用 Reddit 来查看我地区最喜欢的子版块。但总的来说，我喜欢的内容已不再存在于传统的社交媒体上。
