Well, a rant talk wouldn’t be wrong IMHO. I think bringing up painful subjects is important. Talking only about things that work fine doesn’t bring any progress.
I’m not sure what exactly you want to talk about, but maybe you could have a look at Etwas was ich schon immer über Ansible wissen wollte, aber nie zu fragen wagte. It’s about whether Ansible is really simple or not. It’s in German, but maybe it gives you some ideas. Sounds like some people think Ansible isn’t simple (enough). Maybe there are reasons for this, but on the other hand they potentially have a point.
