On the one hand, this question here about what RPG.SE is, and this answer here about answering FATE questions, specify "[this site] is a collection of expert knowledge" and "Expert questions to be answered by Experts". On the other hand, the help page states
Anybody can ask a question

In the question about FATE, one bit of an answer stated:
It seems like people are so bogged down with non-expert fate questions that the first instinct is to give an answer suited for a beginner in the system and not an expert.
This points out that there are non-experts asking questions, that they are many (how are they bogging down people otherwise?), and that they aren't really welcome (at least, not by the answerer): they ask the "wrong" sort of questions.
So which is it?
I ask because I'm not an expert on D&D 4E, 2E, Numenera or Fiasco. I just play and GM them. I have very limited time and chances to play, often having dry spells of months between 4-hour sessions. I enjoy rereading my corebooks and splats, but without actual playtime, my questions and answers will never actually be of "expert level".
The help page is inclusive, and makes me feel I can actually ask questions here. The first answers and comments cited don't, they make me feel that I can at best lurk and check from time to time if something interesting shows up. In the end, I feel I'm almost restating this question, though not exactly.
