**I think we should limit it to questions for which RPG experts are the ideal resource for answering the question. A question better answered by some other group, whether it's another StackExchange site or the wider Internet, doesn't belong here.**

A question about the speed of water travel, such as [this one][1], should probably be on a [history site][2]. A question about dangerous [real-world animals for a no-magic setting][3] should probably be on a [biology][4] site. A question about a setting based on novels/movies/etc, such as Dresden Files or Star Wars, should probably be on the [fantasy/sci-fi site][5]. A research question about an RPG setting, such as [this one][6], *would* be a good fit here, unlike any of the other sites mentioned.
