W3C Social Web Incubator Community Group (SWICG, aka SocialCG)'s re-opened its public mailing list, "for discussion of standards or implementation experience/ideas for a decentralised [distributed / federated] social web".

SWICG "continues the work of the W3C Social Web Working Group" - which standardized ActivityPub. More info: https://www.w3.org/wiki/SWICG https://www.w3.org/TR/activitypub/#sotd

Discussion on the list has begun, e.g. https://lists.w3.org/Archives/Public/public-swicg/2022Nov/0003.html "Thoughts on directions for a rebooted SWICG"

Posting to the list requires joining the group: https://www.w3.org/community/SocialCG/
