Recently, WordPress announced official support for their ActivityPub plugin. Just install it, and it’ll turn your WordPress site into a Fediverse server.
And, listen, for anyone running a webcomic, this is a very cool idea!
If you have your own site, you probably have an array of social-media accounts where you post update notices, which is good for your reach but a pain to keep up. So, what if, instead of your readers on Twitter following your Twitter account, they could just follow your comic site from their Twitters? Or their Tumblrs, or their Instagrams, or whatever else. You don’t need to crosspost on all the sites — you don’t even need an account on all the sites — they act like RSS readers that can all pick each other up directly.
