Weird idea: Create open source characters with stock relationships and plot lines that anyone can use and expand on. Community owned IP, that anyone can develop and treat like their own.
It'd be neat to see a community like, for instance, Star Wars fandom, where the universe is treated like stock material that anyone and everyone can modify to their own needs, but based around designs and ideas that you can use for free.
Just something that occurred to me while listening to someone talk about Commedia dell'arte, where performers adopted a set of stock characters that they could perform anywhere.
