Writing allows for long range communication between people. That can be in terms of distance and time and is a wondrous invention of the human mind.
The first instrument for writing was the hand, then the printing press and now the keyboard. And our reach is now fantastic. In my youth you would have to write something a publisher would think worth while and it would appear in print on paper. Now, with the internet anyone can shout out across the planet and be (possibly) heard.
For a long time I thought that this democratisation of publication was not for me as a producer as I believed my life so ordinary as to not be of any interest to anyone. This is certainly so still. But, as there are so many idiots out there decrying their nonsense I have finally decided that one more idiot doesn’t really matter and I shall pass on my wisdom to the world.
