SO had always allowed and encouraged beginner questions, actually. These days the same question would likely be closed as a duplicate, because the question, presumably along with a good answer already exists.
So that's an example of a good question, actually. And an answer "read the docs" would be down-voted as unhelpful and quickly disappear.

The obvious response is "lol don't you know how to read the doc"?
Yet the view count is over 100,000 and counting, with people commenting how much they appreciate finding the answer immediately.
