I posted this to document the current situation.

I actually wonder if it would be better to migrate all the git questions to poweruser, because they are about the use of a program and not coding.

Git is specifically a versioning system for code repositories, so it 100% belongs on Software Development.

Git questions should all be banned for every community other than this one, except for in cases where the question is very specifically not for a development/programming purpose, and the answer would differ significantly. For instance, Linux can accept questions about how to use Git for non-development purposes, such as dotfiles for a casual user, or similar, but should turn down questions that fit here.

Agreed

Meh. I think that's a little too far, but if there's broad consensus I'll take that into consideration.

It’s not so much about me not wanting exactly Git questions everywhere, I just strongly support limiting topics to as few communities as possible. Overlap isn’t good.

Now, for Git specifically, that is something I’d expect to find on Software Development, so seeing such questions in other communities, kind of bothers me.

Additionally, with topics not overlapping mulitple communities, it becomes easier to manage it, with respect to quality assurance, duplicates, content coverage, etc.
