General remark for startups wanting attention on HN: it's not good to end an interesting article with a call-to-action that makes your article feel like an ad. Readers who read to the end experience that as a bait-and-switch and end up feeling betrayed.
What works much better is to disclose right up front what your startup is and how it's related to the article content. Once you've gotten that out of the way, the reader can then dive into the (hopefully) interesting content and end the article on a satisfying note.
Btw, I have a set of notes on how to write for HN that I'm working (slowly) on turning into an essay. If anyone wants a copy, email me at hn@ycombinator.com and I'll be happy to send it. It includes the above point and a bunch more.
As a reader I’d have appreciated the original. And I’d appreciate a nice HN alternative.
