I've noticed several times people posting the first Google result, or a Wikipedia copy-and-paste, for a not-very-useful answer. For example I asked How long is Kai's brace cable and how does he carry it?, and got a Wikipedia paste (the article itself is unsourced) amounting to "no one knows" as an answer.
But I'd already read this article, and found that it didn't say, which is why I asked here in the first place. "I don't know" is not a particularly good answer unless it comes from an authoritative source like the writer. "I don't know" is not made a better answer by making it "I don't know, and neither do Wikipedia or Google" - well of course not, if those resources could tell me the answer the question wouldn't be acceptable in the first place!
If our policy is "if Google answers the question, it's a bad question" shouldn't a similar policy hold for answers of this type? "If Wikipedia doesn't know, that's not an excuse to never know"?
