Interesting read, since many of this type of articles I've read are from a perspective of failed startups and entrepreneurs, in your case it has been a side project that got successful enough to fund by itself while earning you some extra cash.
This is awesome! Thanks for creating and sharing it at a reasonable cost.
You're welcome! I wish more people would do retrospectives on their 'Show HN' projects a few years later. Especially if it went belly-up, because sometimes those stories are even more interesting and insightful!
