Besides fermenting vegetables, I've been working on adding #ActivityPub support to @sutty through #DistributedPress these past weeks. We ended up with a caching plugin for httparty and a #ruby API client for DistributedPress. This client can also pull and dereference activities from remote instances using HTTP signatures, so it could double as an AP client too.
So when a website managed with Sutty gets a comment/follow/like activity, you get a moderation queue where you can decide what to do with it.
We're also hosting workshops with collectives so we implement features that are useful to all :D
