To clarify first, I'm not trying to get rid of this policy. I'm just trying to ask if there are any better signs that something might be high concept before I waste my time and the curators time writing questions and responses in the sandbox when it could be saved with just a bit more thinking on my part.
I think the title sums this up pretty well. I have so far asked one question (the isolationist dwarves one) on the main wb.se site that from the response seems to have been alright (But if I just got lucky with people answering when they shouldn't have, feel free to tell me that) but one thing I've noticed is that the go-to phrase said to new users is not very helpful. While yes a topic being capable of having a book written about it is generally too much, I can imagine (while yes, often particularly dry but still decently long books) books written about many of these questions, I could even imagine one about transportation between floating islands if they were kept treacherous enough.
tl;dr I have some other questions in mind but I'm hesitant to put them out there and be a nuisance if I still need to do a bit more work on them or even just scrap them entirely and figure them out on my own, except I don't know how to tell.
