For dumb questions like this
There's also UX Stackexchange which I've found useful a few times. I guess it depends on what kind of questions you need to ask, and the kind of community you want answering them
I used to be heavily involved when it launched. I found the community guidelines to be restrictive to good UX questions and answers. It really stifled growth and useful discussions. UX isn't always: "The answer is X" and thats the kind of stuff SE was looking for.
Not as popular as Stack though
I have answered couple of questions before there;
"We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed."
Then I removed my answers even though they were correct, but not long.
