It’s subjective but I think a lot more happens in IRC and besides the Systemcrafters, you also have the Guix and Guile channels a join away to ask particular questions.
I’m also still fighting with Guix and Guile but I haven’t even touched Nix so I will be of no help at all.
The community here feels like most only answer if they know the answer or can hazard a good guess. Sadly noobs can wait a long time for somebody helping them to puzzle the problem out. We need more members, that are bored and are in search of a challenge
