But… wikimedia is already self hostable.

Instead of individual, centralized websites there will be an interconnected network of encyclopedias. This means the same topic can be treated in completely different ways. For example geology.wiki/article/Mountain may be completely different different from poetry.wiki/article/Mountain. There can be Ibis instances strictly focused on a particular topic with a high quality standard, and others covering many areas in layman’s terms.

I don’t think something like this exists yet(?), so it’ll be cool to see how this will be like.

Which also means that marxist.wiki/article/communism will be completely different from libertarian.wiki/article/communism. I think I will take Wikipedia’s attempt at impartiability over a “wikipedia” destined to just devolve into islands of “alternative facts”
