You may have noticed me doing research about the technology stacks being used by #ActivityPub apps, this is because I'm involved in a couple federated projects (both of which are new use cases, and extending the #ActivityStreams format).
I'm open for feedback & collaboration requests!
social.coop is a cooperatively-run corner of the Fediverse. The instance is democratically governed by its members, who generally share an interest in the co-op model, but topics of discussion range widely.
Our instance is supported by sliding scale contributions of $1-10/mo made via Open Collective. You must have an active Open Collective account to apply for membership; you may set one up here
