On Reddit, communities could have their own wikis or knowledge base articles in a separate place from where the discussion happened. I don’t see that kind of functionality in Kbin, so I’m wondering if there is a federated wiki type of thing somewhere out there.

Decentralization is what I’m after, not necessarily federation.
