If there are people who need an answer, and people happy to provide that answer (and perhaps a bit of kind coaching on how to find answers in the future), what is the downside of letting them connect on stackoverflow? Nothing is forcing people to hang out in the novice area answering repetitive questions if they don’t want to.
The downside of disallowing ‘unworthy’ questions is that people feel made stupid for asking, and unwelcome. Also, people feel made stupid for answering, and unwelcome. There is plenty of elitism in tech, and you could keep the main stackoverflow for unique, well-asked questions, as well as adding the novice area.
The advantage of having a novice area of stackoverflow is that more people will use the site. While not every question will be great, the total number of great questions, and the total number of people helped, will be higher.
