Very well written tutorial post. Here are some points.

• The post you wrote is straight forward and easy to understand.
• This is easier to read and follow and not a blog like post.
• I liked D-Steem my self because in some cases it's better then steem-js.
  The way you like to make more informative tutorial for already not good documented libraries is good approach , I my self doing same thing over my blog but i found that you are covering d-steem while i was covering steem official api. I found this and this is amazing, thanks for making such neat post :) I am not a mod but a utopian io mod can give you a lot of several tips to improve it even more!
