If you’re asking a question, it’s expected that you actually know what question you’re asking and that you’re specific. This is generally the issue with downvoted answers that aren’t duplicates - they aren’t specific, so are either too difficult to answer or too easy (ie literally typing the question into Google produces the answer). No-one but no-one on SO expects anyone asking a question to be an expert, just that the question is specific enough to be actually answerable. If you ask a question, you are asking it to an audience that includes experts, and they will give you very good answers if you actually ask a reasonable question. They will not read the docs for you.
This doesn’t preclude being a complete newbie, but as it’s expected that you can Google and read documentation, you need some familiarity with the subject (or a similar subject) you’re asking about otherwise you don’t know what to ask.
Just as an idea of why SO has this [somewhat deserved, pissy] reputation. From my point of view I’ve poured huge amounts of time and effort into where I’m at. I rely heavily on SO for specific answers to issues that crop up. For SO to be useful, those questions have to be specific and good. It does genuinely feel slightly insulting when someone posts something that either would have taken minimal effort (say just typing it into Google), or is a “do my homework for me question” . I get why people feel it is a bit forbidding, but also I feel very strongly that it that’s the way they feel, then they don’t quite understand why SO is useful and good, and should go ask their questions somewhere else if it pisses them off - it’s too useful a resource to risk polluting.
