It’s not that bad once you get the hang of it, especially using a wiki farm like http://www.miraheze.org/

I wonder if it could be done with a MediaWiki plugin, given how extensible MW and its plugin system is

Fair, though that is a somewhat different scenario. I can completely disengage with .ml and still participate in other instances, and the developers don’t get any support from that.

Good recommendation algorithms don’t change the fact that the platform is owned by someone who is actively staging a coup

I suppose the fediverse in general.
