Thanks Gavin - that's the sort of info that will work for me.
Muses Success lists about 500ish, but no way for me to know completion rate.
Juke Pop Serial I think has about 100 or so stories, but none are complete to my knowledge.
Reading past posts from this forum and the now quiet Novelr, I saw a lot of discussion as to why webfic wasn't making more traction. But given the small presence of webfic on the web-- it's hard to see why it would . (In contrast, there are tens of thousands of webcomics on the web according to Mark Waid and other bloggers.) Add to that the rather dismal rate of completion and well.. it's not good.
So... kudos to those who do finish... you guys are a rare lot it seems.
