Honestly, those aren't even the right questions he's neglecting.<p>For example, you can't just add PayPal integration and be like "now I'll get paid". The questions are: what's the MVP for the free app? What am I going to hold back for premium, and why? What do I think the right price is there, and why?<p>If you're making an app just for yourself, and you want to share it, post the code on GitHub. If you're trying to sell a product, let me tell you something: blog posts aren't marketing just because you posted something you wrote.<p>All "business guys" do is resource allocation. We talk to customers to prioritize features; we talk to potential partners to try to enhance distribution; we do the customer service (which helps us further talk to customers); and, yes, sometimes we do the paid advertising and PR and sales calls and marketing stuff.
