Fantastic! This is the (yellow brick) road map I was looking for. Since I first learned of Steemit, I have tried to envision where it would lead. Steembook, Steembay and Steemazon to name a few. But I never imagined, until now, all the real possibilities such as Steemescrow or Steemie's List. Imagine, paying a plumber, who came recomended on Steemie's List with Steem.
