Same with the various web development subreddits as well. Copious amounts of content from "My First Website", to "am I doing intro-level CSS thing right?", and "can I still get a React job?"
There's certainly a place for these, as everyone needs to start somewhere, but having a better home for these would be welcome.
AskElectronics is pretty good though, in large part thanks to Davide's moderation. Losing places like that is sad tbh.
