I initially posted in the Sandbox a question about developing a basic outline for worldbuilding. Comments with a couple of people (lengthy comments) caused it to evolve into the question we now have on main.
We occasionally have people asking about how to go about worldbuilding (Example). The more general the "what should I do next?" question, the more frequently we close the question.
I've noticed similar questions on other Stacks whose purpose is to provide a (growing) list of links people can turn to for the purpose of answering their general questions, leaving the Stack free to answer specific questions.
The question could exist in Meta or Main, though Meta tends to hide things (since searching on Main doesn't list Meta questions).
We could add these lists to the tags, but I frankly consider the tag wikis to be barely useful and they don't appear in searches, either.
IMO, the question (which I'm trying to get converted to a community wiki, just like the answer, so that no one can accuse me of hounding rep) has a valuable purpose on Main.
So, it might be better asked, "Why shouldn't this question be on Main?"
For the record and from my perspective, WB.SE should be THE place people go for worldbuilding know-how. Which is why I think the question belongs on Main.
