You can elaborate on it if you want, the only question is, as @Galastel notes, whether anybody cares. I did not downvote your question, but I know why somebody would; they might think that between the question and the pedantic answer, you provided them with no clear information or advice.
Posting a question to answer it also looks, no matter how altruistically you intended it to be, like you are just selfishly fishing for double points: Points on the question AND points on your answer, instead of getting them the "right" way: Points for your own actual questions to help you clear something up, that invite others to answer and help you, OR points for a good answer to somebody else's question.
Asking a question to which you obviously already know your answer doesn't seem Socratic or educational, it signals to anybody that would even consider answering the question or doing a few minutes of research that they cannot possibly help you, because you have already made up your mind about what a suitable answer is. So what's your point if it is not just a hat on the ground to gather a few tips for bestowing upon us your great wisdom?
I haven't asked any questions I answered myself; but the type I might do is to ask a clear question for something I end up writing about very often; like how a discovery writer (like myself) ends up with a plot. Or just how discovery writing "works" versus outline plotters.
The only reason I would do that is because I see it, in various forms, a few times a month. Writing your own Q&A to improve searchability for what you consider a frequent topic or writing issue may not be so bad.
Still I shy from doing it, because I'd rather my advice be specific to the OP and read by the OP, I don't think people search the site very often to see if their question is already answered, it is much easier to just start typing. If I want to refer to something I wrote earlier for some other poster, I can go to my profile and find my answer there and use the permalink to reference it.
