Re: Sefl-Publishing
You're exactly right. With a few notable exceptions, fiction just doesn't do well self-published. With non-fiction, though, there are some nich markets that traditional publishers don't know about or wouldn't find profitable enough to pursue.
I would kind of like to get back into it, since it was my most sucessful eBay venture. You have to have the right product, though, and get good word of mouth from the hobbyists.
