This morning, I got my copy of Gila Queen's Guide to Markets and realized how many different tech-based publishing markets there are. Likely I was more aware of them because of yesterday's discussion of alternative publication forms. Maybe they've been there for a while, and I never noticed.
Here are two examples of what I found:
Steampod - publishes steampunk short stories in podcast form.
Nanoism is a Twitter flash fiction publisher. Yes, that means 140 character stories or less. They consider serials, too.
Clearly, the world of podcast novels and Twitter flash fic isn't solely in the realm of self-publication. Markets already exist.
In the meantime, I absolutely recommend the Gila Queen newsletter. It's pages and pages and pages (over 70 pages in this issue) of markets for every genre, and each issue includes a section that concentrates on a specialty market. Well worth the $1 per issue it currently costs.
