Hemingway said that when you write a novel, you must write it completely without sharing it. Then let it sit. Then edit it to your own satisfaction without sharing. Then let it sit. Then edit it again. Only then should you share it.

He did all the things mentioned by corra above, then posted his story on NBW. Ann Everett welcomed him to the site and told him he'd be happy here. Jack the Knife told him it would never sell. Seabrass removed six commas. Randall Krzak inserted six commas, Marilyn scolded him for switching POV, JP told him he used too many "was's,"
Doug picked the usual nits, John Hamler told him it it was too British to understand, Gabi told him it sounded too American, Mike Jackson suggested he make a poem out of it, Andrew Hixon offerred to put him in his next chapter, Sol told him his six word short story was too long for the flash fiction contest, Temple told him the story was not yet ready for an in-line. Marilyn told him he could take all these suggestions or toss them where the sun also rises.
John Matthews was afraid to offer any suggestions for fear of insulting someone.
