Is there an equivalent to stack overflow for community related questions?

I feel like there are a lot of questions to do with software development that aren’t necessarily coding related, things like:

“Can someone explain to me where the JEE applet servers and the idea of running multiple aps on the same server came from ?”

“What are some interesting architectures besides x86-64 that are supported by gcc and making a comeback ?”

“What are some easy to get into mailing lists related to OS porjects centered around this language/domain ?”

… I feel like these kind of questions would be in a sense programmer related, as in, a programmer is best suited to answer them, but don’t really fit stack. Is there a website in the se network that’s dedicated to such thing ? Or any plans to build a new “branch” of so that deals with this type of stuff >
