A federated wiki the focus on fighting Wikipedia from a developer of Lemmy. I don't like their cause, but I'm interested in the technical aspect (I myself had been trying to come up with an excuse for using ActivityPub for wikis for two years). They seem to use WebFinger usernames like that: article@server! Wild! Their treatment of media is unclear to me right now, also they seem to federate Markdown, which is just ridiculous for a Wikipedia killer. Wikipedia uses infoboxes a lot, how are you gonna replace that?

Long cool article about the Wikipedia redesign. Nice pictures!
