Yes! This is the plan. Each category in Software or Programming is ready to be federated. So far, only a couple are: Software > Discourse and Software > NodeBB, maybe others. It’s up to each software project to activate ActivityPub in their category and federate with their own channels on the Fediverse.
Note that this discussion is taking place on fedi.
It took some time for own to eat our own dogfood, but there’s no more barriers for this community to embrace the Fediverse fully. The Standards > Fediverse Enhancement Proposals and Fediversity discussions are federated. Federated SocialHub Categories maintains the list, and we can federate more.
I guess what it missing is a directory of all Fediverse actors involved in the AP development processes, so they can follow each other. In this scenario, the SocialHub would simply become an aggregator of memory, enabling knowledge building from the scattered flow of discussions, where curators can pick and quote relevant parts into something actionable for everybody.
