storygen.org
During their GDC presentation, Chris Martens and Rogelio E. Cardona-Rivera announced storygen.org, a site that catalogs story generators.
They have several systems listed, and hope that people will submit more. Most interestingly, you can download the systems yourself and use them to generate stories. This might take a bit of work, since they aren’t necessarily designed for general-purpose use, but it’s still cool that you can try out Micro-Talespin or Talk of the Town.
I hope that this leads to new people exploring these systems and more story generators being submitted. Next NaNoGenMo should be interesting.
