StackExchange makes an important point:
“if everyone using your technology knows everything about it, that means your community isn’t growing. A healthy technology environment includes a stream of newcomers that are learning the basics, as well as experts testing the platform’s limits.”
If you’re not getting as many questions, you’re either not getting enough newcomers or not getting experts testing the limits of the topic.
The experts want the cutting edge, new ideas, and advanced topics to explore.
The newcomers need a safe space to ask beginner-level questions.
