I've said it before, and I'll likely say it again: I write for me. Much like you say, passion is the key. I would be writing my D&D/TTRPG/Worldbuilding stuff offline even if I wasn't on HIVE (and in fact most of my drafting IS done offline these days), and I post for like... 4 people who read my stuff. Been doing it... five years now? Not about to stop, and I see a number of the folks I enjoy reading doing exactly the same. While we can earn here, it's best IMO to treat it like any other blog - love the stuff you make, and let it stand on its own.
