A while back I've seen a podcaster (I think Pierre Rochard?) using a service that crowd-funded next episodes for the podcast. So there was an amount set, and when that amount was met, the next episode would be made.
I forgot what service was used for this.
Does anyone in the bitcoin/pod space know?
I'm thinking of implementing such a system for parts of my podcast.
