There doesn't seem to be a place within the stack exchange network for general questions, website support, or an FAQ, and the "rules" (the tour) are extremely vague and unhelpful.
Users and mods can be very hostile to new members, over very petty issues, which supposedly break (non-existent) site rules or community guidelines.
On meta specifically, posts can be marked as duplicates (when they aren't, or when previous, supposedly similar questions fail to answer the question being asked), and either users or moderators are very quick to down vote questions which they "disagree with". I don't understand how someone can "disagree" with a question ("I disagree" is not a reasonable response to "why is the sky blue"), but that is the explanation which has been given.
I think that these are real problems which could be solved with a few very simple additional features.
I am not asking why the community is hostile (I'm merely pointing out that it is), but I am asking why there is not a better (or any) set of clear and understandable rules and guidelines, or a place for general questions and support, or an FAQ. and maybe a feature to prevent downvote abuse/brigading.
(For an example of brigading, observe the 200 downvotes that I'm going to receive for posting this completely reasonable question, while likely not receiving any reasonable answers)
