I've posted a summary of everything we've learned, collectively, about web fiction in a post on Novelr. I hope this helps, especially if you're new to web fiction. And if you're not new, well, I hope it provides some insight about this thing that we're doing.
It's been some time since I've looked at the older ideas, by the way. If you see something odd, or a post that's just wrong - let me know in the comments and I'll respond as soon as I can.
