I've been noticing a pattern of people closing questions as not Worldbuilding which to my mind clearly are Worldbuilding. I don't want to get too hung up on this specific example, but I don't have a good way of viewing closed questions by close reason and this is the one that I just saw:
Someone's building a fictional world with a space elevator and they want to talk about seeing the space elevator in the sky -- where in the world might they be? Now clearly this question has problems. For example, we don't know how the counterweight is designed. Is it just an extended cable? Or a satellite? Perhaps the author did too little research. But that's a reason to downvote, not close.
The original version did not make clear that it was a fictional question and not a real question. Is claiming fiction a requirement? Should every question include "This is for a fictional world" just to check off that box?
One could argue that this question might be askable elsewhere. But that's a bad reason to close. One, overlap is inevitable. Two, more reality-based sites don't have the speculative background that this site has. If someone wants to ask about the current NASA budget, this is the wrong site. If someone wants to speculate about the results of doubling the NASA budget, then this is the right place. If someone wants to speculate on what would have happened if we'd gone on from landing on the moon to building a moon base, this is absolutely the right site.
No one's ever built an actual space elevator. To me, that makes questions about what a space elevator would be like on-topic for this site.
Part of my concern is that "off-topic" is a terminal concern. It's essentially saying that the question doesn't belong on this site. Unlike "too broad" or "unclear what you're asking", it doesn't lead to natural fixes (narrowing or clarifying the question).
