1. My rules are not any different from yours. I doubt you'll learn much from them given what you're already doing in your repo.
2. I feel that the "what to hide" / "not to hide" choice is too personal to be reusable by anyone else. I'm sure some of the stuff I hide will be considered excessive, and some will be considered missing. What I enjoy in this HN thread is that we share the { practice, tools, docs, tips }, then to each their own :)
3. I'm not interested in maintaining a public repo of that kind of stuff, and/or replying to Issues. So, would rather not make it public.
Sorry/notsorry ¯\_(ツ)_/¯ , at any rate, glad we're sharing tips around the practice.
You could share them publicly without having the burden of replying to issues/PRs etc. But I get you.
