@maloki Perfectly reasonable request, but I wish the tech could help us more, via 3rd party tagging. If I follow X and Y, and X posts something, and Y adds a tag to it, let me experience it tagged. CW and hashtags are both tags for this model. This also means you can always tag your own stuff later, when you realized you oopsed.
Some folks will never tag their stuff, so hopefully they'll never be followed by people who want tags, but content can be boosted+tagged.
