If you’re determined to join a group like this, the Nix/NixOS Matrix is a better option since it’s already 4k+ strong.
It’s also official and its logs are published here: https://logs.nixos.dev/ so the discussions happening there should (at least in theory) show up in search results instead of disappearing forever.
You may wish to look into NixOS or GNU Guix as taking the same ideas to the logical conclusion, or stal/ix which aspires to take a more traditional approach and in that way is perhaps closer to Gobo. All three are very much alive and actively maintained, even thriving by some metrics.
