Okay, so right now I'm working on an entirely new system for the hopper (pulling data into the site itself, rather than sideloading a Google Spreadsheet via javascript) This allows for a couple new ideas of stuff to be had in the hopper. Let me give you the rundown.
Originally, we had just a list of documents that nobody could see. That started to become a problem when we'd be getting duplicate submissions, so we built a new system where people could see both submitted content still under consideration and submitted content which has been rejected.
I've changed how that data is stored/conveyed a couple of times, but the approach has largely stayed the same. Documents in the hopper are kept private to the F+ reader group, until such time as they're recorded & released when they go in the show notes, or when they're rejected, when I publish the link.
The germ of the idea is that I worried that the documents would serve as "spoilers" for the episode if and when it was released, and I still think there's some validity in that thought. However, that's balanced against the idea of holding back content from people for reasons that seem a little abstract. It could be useful for more people to know the content of the documents we have, so that we'd get better direction on where to go next - as we're standing at around 80 documents still marked under consideration, it can be very difficult to pick one to do next.
So, that's my thought process currently. If you have a case to be for why documents should or should not be made public, make it here.
