r/embedded feels like it has become 75% "how do I find my first job as an embedded programmer", which gets old after a while.
AskElectronics is pretty good though, in large part thanks to Davide's moderation. Losing places like that is sad tbh.
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.
While I sympathize with newbies, the incessant “My First Blinking LED” posts get old really fast. Especially when said LED DOESN’T blink, and they post a Fritzing thing instead of a circuit diagram.
