I actually have a post about it, and how it becomes a useful point of reference for the Edgeryders vision (if there is such a thing): Exit vs. voice: reacting to decline in 2017
About sharing stories: I personally do not write that kind of stuff, but I am happy to read it. The Dark Mountain crowd, including some folks close to us (notably @hexayurt), used to do this sort of stuff a lot: people would contribute pieces of speculative fiction, and then they would make an anthology. I guess it could be done in Edgeryders too, if someone had the drive to lead it and pester people to write their pieces.
