The radio dial is one big app for content. And now Apple borrows the "radio dial" metaphor to distribute podcasts. Not just the ones you already subscribe to but others like them. It's a much lower usage threshold bar (always one of the biggest problems with podcasts) and if, as rumored, this app becomes standard issue on the new iOS the threshold will become lower still. This creates lots of new and convenient alternatives to the "spoken word" content that listeners get today from that other convenient source of non-music audio. The one called "radio."
