Ask HN: Are there any good communities for QA Automation?

I am changing responsibilities currently from backend software to (cloud) system quality. I'm going to be spending a lot of time looking at various forms quality (security, availability, compatibility) and making tools and tests.

I've been thinking about the role for a while and have a lot of ideas of the kind of things that I could do, but I've never worked with someone with this role as I imagine it.

I've done a fair amount of work in these areas while working on server code but now I want to get really professional about this. Is there a community with people discussing this area? Ideally it would be covering topics such as (CI, TDD/BDD, load/stress testing, fault-tolerance, chaos injection, application security, data security, penetration testing, static analysis, monitoring).
