Why do you think the creators chose audio as the medium?
I believe it sets the tone of an apocalyptic world, because they would not have TVs nor internet. Radio signals can move across the world and is very reliable for communication.
How well does the crowd-sourced audio work to tell this post-apocalyptic story?
It they tie together is by having a source of communication that can be reached by anyone who is at the right frequency. Thus, creating a sense that the whole world has gone to ruin and looking for help and answers.
What would you do differently if you had created this story?
I would not do anything differently, I believe this idea is awesome and could reflect what it would look like if the world was to end some how.
How I contributed?
I created an entry of a man who has run out of resources in the bitter cold begging for help as he has a child to care for. Why I threw in the child is because in a post-apocalyptic situation the population is depleting and they need to keep procreating in order to prevent the human race to go extinct.
