I'd love to support podcasters more, but do people want to discuss podcasts in this particular text format? I'm not sure.
Other than discussions, what value would we bring podcasts? Ranking? I could see that a little more clearly.
On discussions ...
Good discussions require a coincidence knowledgeable people wanting to discuss something at roughly the same time - which is already rare even for 5 minute long article reads. In the case of podcasts, it's a 1-3hr time commitment in audio and/or video format and then switching to text to discuss it. Meaning, I think the coincidence rate is even lower for podcast discussions.
