Hey y'all - I've been developing a free webapp for collaborative story writing at FractalWriting.org, where users respond to a prompt and then to each other's responses, building off each other's work in a fractal pattern of creative branches. If anyone here feels like experimenting with that idea, I'd love for you to swing by and give it a whirl. You can create your own prompts, but I've also created a prompt for new users who just want to jump in. Let me know if you like it and either way, I'd love some feedback. I'm continuing to tweak it every day. Thanks and have fun!
