Maybe we need a better term, but all media should be decentralized. Like a website. Anybody can put it up and anybody can access it, nobody in between. Podcasts are like that. #Castopod helps. #Peertube does it for on demand video. #Owncast does it for live video. #Azuracast for radio. #Ghost for articles. There are others.
But our biggest need at the moment is in consumption. Better tools for those who want to access this stuff, manage it and handle recommendations. Great app developers.
