Is there something you find wrong with that? I generally find comments on HN to be thoughtful and people tend to invest some effort. There’s also a surprising amount of subject matter experts lurking until their subjects come up. A “prompt article” seems a decent way to get some of that going, no?
Then it should just be posted as a text post. No need for this to be posted more than once as well. I don't find low effort attention grabbing interesting or helpful.
