Cool story! Makes me think I should write my own up someday.
However, one thing I find odd. The story talks about the creators and how important they are. But when I go to gumroad.com looking to see all these creators, I see how to sign up as a creator, but don't actually find the pages of other creators. Where are they all? After reading the article, I don't get how the business works, I guess. The article led me to believe it was similar to Etsy where creators sell their wares. Is that not the case here?
