I didn't know publishers actually went through those NaNoWriMo novels. I guess you have to publish them on the site? I wonder if anything good ever came out of that. I do like the feeling of writing stuff. I don't know why, but it's cathartic. There's nothing I wrote that I'd consider publishable, but it's fun.
I had a friend who had a novel that originally staretd off as a NaNo project get accepted somewhere, but she was also one of those writers who wrote every day regardless - and would rise as early as 4 to do so if need be. So the circumstances aren't typical.
This I do not know, and it is a college friend I have fallen out of touch with so I cannot ask. I will say I think she substantially edited and revisited it before sending it out, it wasn't just a "let me spawn this onto a screen and get it published." Finishing work was involved.
