As someone who very much enjoys podcasts I continue to be frustrated that so much information is locked up in opaque audio files. How do we make all of this information accessible, searchable, navigable, linkable, upvotable, etc? Great opportunity if someone does this right, imo.
When everything is measured in terms of engagement, content will be optimized for addictiveness. Not entertainment or artistic merit. Not intellectual substance or creativity. Pure, plain addictiveness.
