Excellent post with brilliant content!
In terms of keyword tags, I often thought it might be more streamlined if we were to use the ones proposed by the DEWEY System while adding up extras from the multiple official libraries in the world today. From there, expansion can easily hit in the newness and creative aspects.
I have ben sharing posts from multiple authors over Facebook and out of my personal emails as well. I sure hope more and more people do the same in propagating the knowledge and different kind of information/stories present on our platform.
All for one and one for all! Namaste :)
