a question for the writers

I write better/more quickly when I have an audience. That's why I've released books as serials for years--if I kinow I have an audience of people who are waiting for the next chapter of the story I'm writing, I write more, and more quickly.

Problem: this is a form of self-publishing, and it really limits future publishability of the work. I would love to post the Newfoundland book rough draft as I finish chapters, but I honestly think that book has publication potential once I finish it. Of course, the problem is...will I finish it if I don't have that immediate feedback?

I don't know. I'm considering writing a couple of things that will just be online serials--a few other people are doing that, and actually making some money off of it.

Thoughts, anyone?
