How exactly would you expect someone to ask questions when you don't include a way for them to see what you're talking about?

My first question to your original post would be: "where's the link so I can see what you built?"

That's okay. On HN, unlike Reddit for example, self-promotion is fine, as long as it's done tastefully as you've done. There's no problem with posting your link in the original post, people actually want to see what you've built.
