I imagine ability to fork, comment, open an issue or a merge (pull) request, do a code review etc from an account on one instance to a project on another. That would enable true decentralisation of software development. It was one of the original promises of Git, but was lost with the emergence of GitHub. With such federated network of forges each developer, or a group working on a project, could run their own server and collaborate with anyone else, without registering accounts on hundreds of services. I’d love that.

What’s a better alternative? Which other platforms are you referring to? How do they compare in terms of features and adoption? From all the decentralised, e2e encrypted platforms I tried, matrix is the only one more or less accessible for normies.

That wouldn’t apply to conversations you have within a group that hosts their own server, would it? Like within a family or a club.
