Because you see, I can't play the ukelele.
The book world has become a mall in which many are strumming an instrument they cannot yet play. New writers are there practising, and some readers might stop to 'listen', and even throw in a coin as encouragement. Some might not even notice that these newbies can't play, which is fine. It's okay for people to entertain each other at any level.
So what, you ask - is it acceptable for sub-standard writing and amateurish books to flood the market, to be bought by unsuspecting readers? Well - the answer is complicated and far too complex to put inside one of these blog boxes, but the short answer is yes.
Yes! Yes? Yes - when an industry is democratized, anyone can play. Writing and reading do not make much noise, so it's all right to 'busk', even if you still not have achieved 'the' standard, something that used to be decided by gatekeepers before all this democratization began. When something is democratized, it is by definition decided by the people. In this case, the people who read and buy books. The process is known to us - we vote. We also vote with our wallets when we purchase books, and we buy what we want. It's not so hard to find out if a book reaches our standards.
Very, very basic economics, I'm afraid. Because in addition to not being able to play a ukelele, I cannot do much with economics, maths, or metal work. I am useless at sailing too. But I can write a mean book. I have written and published several, all on my own. I'm an independent author who has been 'busking' for some time. And amazingly, people stay to listen, because by their judgement, and no one else's, they regard my books to be useful to them. Because no one else has decided but me whether the books are 'good', or 'ready to go', it's up to readers to decide whether they want them.
Democracy is probably not perfect, but it's the only system that works well for decisions that involve transactions and interactions between people. It might just work for creating, buying, and selling books. Because you see, it is perfectly possible to walk away.
Tell me what you think about the concept of utility and democratization of industries.
