I submitted the website on Hacker News and 1 hour later I realised from my analytics that it made it to the homepage!
Got around 30k views from HackerNews & related traffic in the first week.
I got many negative & positive feedback from HackerNews.
Some things I learned: Make it super clear that the product is paid (this was something I didn't think through. Problem is you'd only see the payment page after you finish all the free content).
I ended up patching it quickly and adding a Free Trial icon so that users would expect that there's a payment somewhere.
