> Alternatively you could federate it. Maintain wikipedia as the primary instance but allow users to add secondary, wikipedia community vetted wiki instances Nowadays, Wikidata is playing that role already. Its concept of "notability" is flexible enough that labeled roads or individual Pokemons could handily fit there - if something is described to some minimal extent by a verifiable source, it can go in. Each Wikidata entry can contain links and "identifiers" that describe or refer to the same real-world entity in different namespaces, and you can use the Wikidata-specific browser extension Entity Explosion https://www.wikidata.org/wiki/Wikidata:Entity_Explosion https://www.wikidata.org/wiki/Wikidata:Entity_Explosion to seamlessly browse to other descriptions of any given entity as you browse the web. So the vetted "secondary" sources you're talking about don't even need to be wiki-specific, they can be practically anywhere on the web.
