The Washington Post Says when it comes to publishing these days, it's all about the platform, as in, "Does the author have a platform to promote his or her book?"
Publishers now want authors to be previously published, a TV personality, a musician, an actor, or maybe a politician.
An author with a regular TV gig or a nationally syndicated newspaper column or a wall full of platinum records is worth way more to a publisher. Such a writer brings a built-in audience and untold opportunities for cross-promotion. Dave, Jay and Conan would just love to put him on the couch.
