i’m a tag wrangler for the archiveofourown, so if you’re interested in learning more about human-assisted organizational structures, feel free to slide into my dms (although I might take a while to respond).
here’s an explainer put out by wired on what i and other volunteers do: https://www.wired.com/story/archive-of-our-own-fans-better-than-tech-organizing-information/
i don’t think it’s a stretch to say that ao3 has the best tagging system on the internet from a user perspective, but you don’t get a system that good unless you pay the price, and take the tradeoffs. but yeah, just putting this on your radar if it wasn’t :)
eta: I don’t expect this to be a feasible solution for lw, this is more to broaden your scope on what’s out there so you can make a better informed decision at the end.
