They are saying you should have just posted the link in the top/original post itself rather than as a comment. That's usually how it goes on HN so that people don't have to search for your specific comment with the link, they can just go to the post and see it there.

Wanted this to be more of an AMA on the what and how vs “hey subscribe”!

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.
