I've considered doing this if I can't pick up an agent. I already have an idea for a second novel. It is not a sequel, but would be a similar genre. My thoughts are that it might generate interest in my work while I start a new novel, building off what I've learned from writing the first one. It probably won't make much difference to agents, but at the same time it probably wouldn't hurt to build a fan base. Surely there's 1 person out there who would like what I've written. I would call that a fan base, lol. Anyway, looking for thoughts on the idea.
