This question is mostly meant for gathering ideas for an eventual [about](https://topanswers.xyz/meta?q=640) wiki post and to make posting a first question less intimidating.
I think a good approach would be keeping the topic broad at first and act as a temporary home for other broadly related communities (e.g. about other JVM languages) until they gather some momentum. Apart from this, before we establish some more community specific guidelines a link to the TopAnswers [code of conduct](https://topanswers.xyz/meta?q=8) should be enough.
Other community related topics (including the colour scheme and logo) or more specific aspects (tags, post types) can be discussed in a dedicated [meta] post.
