Yeah, I’ve been experimenting with YaCy, and discovered they have a PageRank-like algorithm, but it uses a lot of resources, so they don’t recommend using it and it’s turned off by default. Haven’t tried turning it on myself. Looks like the maintainer is focusing on YaCy Grid, meant for organizations, not general decentralized search.
Some states are pretty authoritarian and stop cities from doing anything good. Some states have banned rank-choice voting. But yeah, where this is possible, it’s definitely a path forward.
