Every year this happens--every time someone starts a thread about posting their Nano novels online, someone comes along and shoots it down because it's supposedly bad to do so. Publishers. First publication rights. Yadda yadda yadda. I think someone should put some disclaimer to that effect directly on the FAQ so everyone could read it instead of having threads getting hijacked by know-it-alls who think they're doing what's good for you. Just like those terribly overbearing mothers who want to take over your life.
And yes, before you start lecturing me, I know all about first publications rights, the idosyncracies of publishers about online fiction and the like. I don't plan to take the stuff I've written during Nano directly to a publisher--this kind of thing requires massive rewriting and I doubt the final draft will have any resemblance to the first one.
