In most cases, talking of self-publishing, you're right. Most anyone can clean up copy, though, friend or not. Professional writers I know, including an American National Book Award winner with a new unpublished work of historical fiction, have no ego when it comes to passing along their work for criticism to friends with distinguished credentials. I've often thought there are dozens of members who could produce a successful gun book for the general market from contributions here, if they put their mind to it.
