A few months ago, the Journal wrote a piece about the demise of the slush pile, that undifferentiated mass of unsolicited ideas from authors and screenwriters in search of a publisher or studio.
They missed the point.
In the words of Michael Brooke, "I'm not interested in creating slush."
If you have something good, really good, what's it doing in the slush pile?
Bring it to the world directly, make your own video, write your own ebook, post your own blog, record your own music.
Or find an agent, a great agent, a selective agent, one that's almost impossible to get through to, one that commands respect and acts as a filter because after all, that's what you're seeking, a filtered, amplified way to spread your idea.
