Listened today. Nice work, I really like these kind of stories (small time internet success stories). I don't know if your podcast has others, as it seems like you're mostly focused on the tech stack of sites. Some of my favourite HN posts are the common "What's your tech side hustle?" posts. I love hearing the stories of people making a bit of side cash on small little sites. Some examples I can think of (however, both are much bigger now) is the Vileda Onions guy, bingo card creator and the wedding table name tag site.
Thanks. If I had to estimate, I'd say about 2/3rds of the episodes are solo developers putting up some type of site (SAAS app, selling a product, etc.).
