HN added this comment based on my submission. I simply filled out the form that was provided for making new submissions. Sounds like if users don’t want comments like this that HN should change their submission form.
What dang is saying is that you shouldn't post a summarizing comment with your submission.
Yes, HN has the option of submitting a comment with and when you create a post, but that the use of that should be to provide your own commentary or context, not merely to re-hash the post itself.
And yes, the additional text you provide with a text link does appear as a comment, that's intentional, see e.g.,:
THat's true - if you submit both a link and text, HN's software will (usually) convert the text to a comment. I take your point that that wasn't exactly what you intended, and I'm sorry for misunderstanding.
The idea of HN threads is good, curious conversation, and that requires avoiding formulaic responses, even if they're well-intentioned.
