Interested. I collected some C2S resources together before.
I can offer forum space and matrix chatroom, if you are interested. 'Groundwork labs' on Social coding commons is themed to exploring the foundational technologies of social web / fediverse.
There's no membership, just affiliation. Groundwork labs is a fellowship, where interested parties collaborate, not a community.
