These are two questions that were both asked on Worldbuilding proper asking the same question: what is considered worldbuilding; what is the definition of it? However, I've noticed a few things. Why was the first question closed with 4 downvotes, while the second question, asked more recently, is still open, with 3 upvotes (until I downvoted on it) and 1 favorite? Aren't these both essentially the same question?
The first one is pretty unclear and is just a few broad bullet points. The second one shows some thought; the asker has a problem and a clear question, albeit also broad. I also suspect that once the migration to meta was suggested, people who might have downvoted refrained -- this is obviously somebody new to the Stack Exchange network who didn't even know about meta, so people might have just voted to migrate.
