This question on Dreaming was asked recently. Lets ignore the fact that its also off topic for now. When I googled the question I found that the top result was a comprehensive and well referenced question from wikiHow. As far as I can see, its a perfect answer, but we don't post links and copy/pasting the entire thing seems wrong. (Another example, as requested)
My question is: Do we think that questions that can be answered by a basic Google search show a lack of basic research and therefore should be closed?*
*By basic google search I mean that one place high placed result answers the question in a full and comprehensive way.
In addition: Worldbuilding typically has long answers to complex questions. Were it a case that copying a single sentence or paragraph and providing attribution were the answer, I would probably ignore it. However in this case there is a full length article written on it from a popular (and high ranked) site.
