Good morning! I'm glad to see you're going to go for it, I've got a few ideas that I've been playing with and Craig creating this tag also prompted me to give it a go, even if it is just a much-needed exercise in creativity for me. You don't necessarily have to divulge much about your world if you don't want to, one option is to extract details and make them stand alone when posting / looking for feedback. I would like to point out Andy Weir's The Martian book, he started it by blogging it as he went and so the first version was available completely free online. People asked him if he could make it into an ebook format for easier reading, so he did; people asked if he could put it on kindle as that's easier, so he did; people asked him to make a paper version, so he did; and it became a best seller!
