And? It's not like there's a prohibition against promoting your own startup here? In fact, the "Show HN" posts are very explicitly about self-promotion.

If somebody posts something that's genuinely useful to others (and I, for one, did find this post informative) and it also happens to promote your thing, well, hey... that's what I'd call a "win win".

This is surprising. I clicked your username expecting to see a 47 day old account with twelve karma and an average of 1.2, well on the path to hellbaning, with a fundamental misunderstanding of who this site's core users are and what they find useful.

But no, you've been here from the beginning and you run a software business. You've been seeing helpful articles like this for the better part of five years now and, I assume, benefiting from them. Seems like a strange time to snap and make a snarky dismissive comment.

Bad day?

I found it to be a very helpful post. I learned something that I can apply to my own site.

If such a post gets a few sign ups for planescape along the way, I don't see the harm. But advertising was far from the focus of the post. The author doesn't even say what planescape does.

The article wouldn't have hit the front page if it wasn't useful. How many companies are using retargeting + drip email effectively?

The author didn't even submit this post to HN himself. If you wrote a blog post on your own blog and someone else submits it to HN, would that be considered "How you advertised your startup on HN"?
