The r***it neovim community is fab and taking part in the go-dark outage protest. I think open source communities are better served by open not for profit, decentralized community-apps like this. The corporaate ones always go bad in the end. Reddit and Github both allowed their data to feed the big tech power grab that is LLMs.
Also, you can now follow @neovim@a.gup.pe on Mastodon which is another way to do groups. Following that is like following a hashtag, except that the hashtag follows stop at the server’s boundary whereas the group content is automatically federated.
