I agree with all of this. Just to add a couple of things:

Because of some people's feelings having about politics in !newzealand, I wouldn't be keen to see posts that are clearly about politics cross-posted from !politics into !newzealand. Those who want to see politics can join the community. But I really don't want to disable cross-posting unless it becomes a clear problem. Sometimes it will make sense to cross-post, and I only want to introduce rules where we really need them. Cross-posting is also useful to help people other find communities they're interested in, especially across different instances.

The other thing I want to say is that there are very few of us moderators here, and if they're anything like me, they're already spending more time on it than they should. I'm really hoping we don't need to be reviewing the contents of links and that people will generally post things where they belong. We're going to be adding more guidance about that soon. I'm happy to trust the community at the moment. People seem pretty onto it here.
