ActivityStreams was originally an XML extension for Atom <https://activitystrea.ms/specs/atom/1.0/>. It worked just fine with a static site. https://www.w3.org/TR/websub/ formerly PubSubHubbub was used to notify subscribers, but it was optional and subscribers would fall back to polling. WebSub could be a separate service. The trickiest part is handling replies, which involves some cryptography to prevent spoofing. But this too could be done by polling, only then you only get replies from those you subscribe to. ActivityPub does this with crypto too IIRC. |
