>What I was curious about is why is HN regarded as such a good place to promote your own work, if in general, this sort of posts are frowned upon?
Honestly, I don't know.
That said, I'm not a founder or a software dev, so my interests aren't necessarily that of many others.
What I have noticed is that most people around here are intelligent and erudite.
Which means interesting posts and good discussion.
Perhaps you should check out what folks are submitting vs. what makes it to the front page via the "new" link in the header?
That might give you a better idea as to what will fly around here. While you're at it, maybe upvote the submissions you want to discuss.
Another option would be to look at the submission histories of users you find interesting.
This one[0] from today definitely tickled my fancy. And apparently that of many others, as it has 250+ upvotes and 350+ comments. Check it out.
I get that you'd like folks around here to give your product/service/whatever some love, and perhaps you'll find the right mix to generate interest. Good luck. I hope that works out for you.
