"stupid questions" doesn't sound too bad until you actually experience the deterioration of communities. For suckless I don't think it's a threat, as their specialization already filters the 99 percent. But try to find, for example, a community for experts in Java. I personally think it is a fine language, but it was designed to appeal to beginner/intermediate programmers, and any community around it suffers from that. You wouldn't believe how many people just open Github issues (with nothing but a title - the default issue template left untouched) for any NullPointerException, regardless if it is related or not.

StackOverflow is an interesting case also, they get a lot of criticism for being "toxic", but it is getting difficult to get answers to actually interesting questions. "How do i read a CPU register in C?" gets answered with "why would you want to access the CPU registers ??? It is an low level implementation detail therefore you cannot read them".
