This same principle is exactly what the "publishing" industry will be faced with in just a few years. The book printing and retail business is disappearing before our eyes. Soon, all books will be essentially self-published.
Many good authors who have been unable to past the self-appointed publisher gatekeepers will be available. So also will infinitely greater numbers of writers of drek, who those gatekeepers also kept off the market.
I expect some sort of market or rating based system to emerge whereby people will be able to effectively find stuff they want to read in the vastly expanded universe of that is available.
I would expect something similar for video, music, etc.
Right. On the web, any idiot can throw up a website, but “content is king”. Give people what they want, and you will draw a following, otherwise you are lost in the static. Draw a following, and you will draw advertisers than covet that demographic. It’s freedom of association and the free market at its best.
