Here's a quick list of some places that will list your blog novel. Hope to see more from others.
--Web Fiction Guide
This seems to be the premiere list and review site for online fiction. Aiming at being the IMDB or Google Directory of online literature, it's doing a damn good job. They place your blog novel with a screen shot and there are reviews and ratings, like on amazon.
Only online fiction (no fanfic, erotic, webcomics, or blogs that aren't stories). They check to make sure your site works on all browsers and do some preliminary reveiws and commentary.
This is a five star resource for anybody trying to create lit online.
--Free Online Novels
This site is very writer-friendly and altruistic...and has a link to add your book to their list.
Bills as "The #1 Site for Online Novels" which is debatable, but there is a pretty good list of some interesting reads here. And a link to add your project to their list. Some additional links are interesting, as well.
--The Definitive Blog Novel List
Well, "definitive" is a big concept--and hard to define--but this is an ambitious list and they invite you to submit links to your book. For readers, it's a good list of some innovative online writing.
--Free Speculative Fiction Online
This listing is for speculative fiction and is more oriented to readers than to authors trying to get listed. But give them a shot if you're into SF.
--Google Directory--Online Writing
This is a list of lists, so to speak, and if anybody wants an exhaustive search broken down by categories, here it is.
