If I want to make money with music software, I should probably be making mobile apps, because there is infrastructure set up for people to buy mobile apps, and a culture of people doing so, but that same infrastructure and culture doesn't really exist for browser-based apps. At this time, I don't think I can bootstrap a side-business all on my own, it seems like an unrealistic goal for me to pursue, but that doesn't mean it's impossible for Zupiter and future music apps I create to bring in revenue. I also don't really want to quit my job and live on a sailboat, but I do want to keep creating useful software and content and share it with the world, and it would be cool if there was a way that I could save up enough to take a few months off to work on my side-projects full time someday.
