These are great questions! We have a tech working group and a community working group.
The tech working group is headed by @wu_lee who has been looking into doing an upgrate soon.
We'd love more members to join the WGs. Check out the loomio page for more info! https://www.loomio.org/socialcoop/
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
