Thank you very much @awesomianist for your reply. You got it right that it is a compliment for your description skills. It is true there is a plethora of articles available on the topic but the jargons used by the authors are beyond the comprehension of common steemians. This post is like many others in a way that it gives the same information as they do, but is entirely different from those in the sense that this is so neat and lucid that anyone can understand it. A simple writeup is always the best. Keep the good work up!
