I think a key is to think of FedWiki not as creating 1 giant discussion forum but rather a network of social relations, framed as Neighborhoods.

So, when you’re writing about politics, and seeking wiki-ers to co-create meaning with, you’ll probably end up interacting with a relatively small number of people, and you’ll probably end up excluding people with opposite biases.

Unless your goal is a NeutralPointOfView, in which case you might as well edit Wikipedia.
