Is there anyone here with a revenue stream that is mostly from ads or premium accounts? I'm working on a side project that is essentially IMDB, but for music. As I'm reaching the MVP, I'm starting to think more about monetization, and I'm trying to gather as much experience as I can, but it seems like most successful side projects here sell a product or service, not exactly what I have going on here.
