Throughout its conception, the blogs on Universe Factory were either interviews, story chapters and worldbuilding dos and don'ts. But not once did I see a blog being a what-if question. (The last paragraphs of Great Lakes Earth's geography and solar systems are intended to be what-if questions in a more formal disguise. However, I may not have made them obvious enough.)
So my question is this--can simple what-if questions, particularly those you asked on Worldbuilding Stack Exchange without much success, be allowed in Universe Factory?
