Every writing project competes in the marketplace.

Every writing project competes in the marketplace. It's important to know your competition.

I think it is also important to know your marketplace. Most people I've come across are just writing without paying any attention whatsoever to who might actually read their output, assuming of course that they want someone to read their output! The trouble with markets is that the consumer (hate that word) has far too much choice in this, our 21st, century. The marketplace is global. It's in peoples phones, computers and televisions. They can consume 24-7, but how are they to discern? Write for your ideal reader and you won't go far wrong. It is important to have someone in mind when you put pen to paper, otherwise you may as well, to a great extent, be writing in your diary.
