I did a Show HN a few years ago on another account. It got no upvotes but that website/app has generated over $6m in revenue in that time (over $4.5m profit). Not sure what my point is but thought I'd share
I think HN is a very particular group of people and not representative of the market for a lot of the products we make. We tend to like open-source things, ask lots of technical questions and complain about minute things. Also, Show HNs tend to perform better if they are quick to use (no sign in required, don't need to download, etc.).
mine got lot of upvotes and huge traffic but it died after few days. I think it has more to do with novelty of idea rather than commercial interest.
This happens all the time, it’s a good thing to really keep in mind. All of my best projects were dismissed initially and continue to be. There is a reddit post where I announced Blockheads to a handful of “looks like a crappy Minecraft ripoff” comments. It went on to be played by 50 million people.
